Delivery Date Context Status Description
2024-12-17 hst_1202.pmap latest This is the first delivery of a time-dependent photometry lookup table for WFC3/IR. New IR inverse sensitivities incorporate updated CALSPEC models and include corrections for temporal changes in the detector sensitivity derived from 14 years of monitoring data, as described in Marinelli et al. 2024, WFC3 ISR 2024-06. The automated calibration pipeline, calwf3 v3.7.2 or later, now implements a time-dependent IMPHTTAB for IR, so the image header inverse sensitivity keyword, PHOTFLAM, accounts for sensitivity losses of about 0.1 - 0.2 percent per year, depending on filter. These new inverse sensitivities provide an internal photometric precision better than 0.5 percent for all wide-, medium-, and narrow-band filters, as discussed in Calamida et al. 2024, New Time-Dependent WFC3/IR Inverse Sensitivities. For compatibility purposes, the MJD value arrays contain the previously-published inverse sensitivities as a constant.
2024-12-17 hst_1201.pmap archived A new ACS PCTETAB reference file is being delivered, because serial CTE correction is included in CALACS v10.4.0. This new PCTETAB contains the parameters for serial CTE correction along with the existing parallel correction parameters.
2024-12-12 hst_1200.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from November 4, 2024 to November 30, 2024. Currently, the automated calibration pipeline and CRDS have only WFC3 UVIS drk and dkc reference files with USEAFTER dates of up to October 31, 2024. The automated pipeline should now use these reference files to perform dark subtraction on any UVIS datasets obtained between the dates above, as they represent the most accurate picture of dark current and hot pixels for this time period. These WFC3 UVIS drk and dkc files were generated using dark exposures from HST Cycle 31 CAL program 17349, and HST Cycle 32 CAL Program 17667. More information regarding the method used to create the UVIS dark calibration reference files can be found in WFC3 ISR 2016-08. Additionally, the header of each reference file contains a detailed history section outlining the process, and provides a list of data used to create each file.
2024-12-12 hst_1199.pmap archived This new bad pixel table with USEAFTER of November 4, 2024 was generated using data taken from November 4, 2024, through December 3, 2024. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of October 11, 2024. The automated pipeline should now use this reference file as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because it represents the most accurate measure of pixel stability at the time of the science observation. These WFC3 UVIS bad pixel files were generated using 900 second dark exposures from the HST cycle 31 daily monitoring program 17349 and HST cycle 32 programs 17665 and 17667. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
2024-12-06 hst_1198.pmap archived A new ACS BPIXTAB reference file is being delivered because new image artifact, or flecks, locations needed to be added. Detector artifacts have been monitored since 2017. During the July-August 2024 monitoring, we noticed a new small fleck on Chip1 of the WFC detector. The pixels in the fleck have lower transmissivity and could affect the photometry of the object if the object falls on these pixels. Therefore, we mark the pixels, below the 50 percent threshold, in this fleck as bad and give them a DQ 4 flag. These bad pixels are now listed in this new BPIXTAB reference file.
2024-11-27 hst_1197.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between October 31 and November 27, 2024. The files were generated from data taken in the same time frame under STIS calibration programs 17378, 17632, 17376, and 17629.

2024-10-29 hst_1192.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on October 26, 2024, and should be used to calibrate ACS WFC observations taken between September 23, 2024 and October 26, 2024.
2024-10-18 hst_1191.pmap archived These time-dependent WFC3 IR superdark reference files will affect all IR data taken from HST Cycle 26, beginning on November 5, 2018, to the present. They incorporate several more years of individual IR dark frames than previous references, and make use of updated BPIXTAB files to more accurately represent the dark current in time-dependent hot pixel populations for data taken since the last delivery of IR superdarks. A description of the process used to create these files is recorded in the history sections of their headers, as is a list of the individual dark images used to create each file. Additional information on the superdark creation process can be found in WFC3 ISRs by Sunnquist et al., 2019, and Pidgeon and Khandrika, 2024.
2024-10-17 hst_1190.pmap archived This new bad pixel table with USEAFTER of September 10, 2024 was generated using data taken from September 10, 2024, through October 11, 2024.

2024-10-09 hst_1188.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between September 7 and October 2, 2024. The files were generated from data taken in the same time frame under STIS calibration programs 17378 and 17376.
2024-10-08 hst_1187.pmap archived This is an update to the COS NUV TDSTAB reference file for mode G285M, obtained using the Python analysis scripts analyze_files.py and analyse_data.ipynb. In a previous delivery of TDSTAB, the G285M solutions were incorrectly copied over and provided incorrect corrections. The G285M rows are now correctly copied and contain the same solutions used before the introduction of wavelength dependence. The reference file has a USEAFTER date of 2009 May 11, the start of COS NUV operations.
2024-10-03 hst_1186.pmap archived New STIS FUVMAMA throughputs are being delivered for ETC version 33.1. Throughputs are updated due to changes in the FUVMAMA TDSTAB. There are no changes to the NUVMAMA and CCD throughputs, and these files are evaluated to match the MJD evaluation date of ETC version 33.1.
2024-10-03 hst_1185.pmap archived Updated COS synphot files for ETC 33.1. These include throughput changes due to updating the NUV TDSTAB. These are evaluated at MJD 61131.
2024-09-30 hst_1184.pmap archived This new bad pixel table with USEAFTER of August 13, 2024 was generated using data taken from August 14, 2024, through September 9, 2024.

2024-09-26 hst_1182.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated follow the ACS WFC anneal on September 23, 2024, and should be used to calibrate ACS WFC observations taken between August 31, 2024 and September 23, 2024.
2024-09-16 hst_1181.pmap archived New ACS WFC synphot throughput tables are being delivered with a new extrapolation date for ETC 33.1. The default THROUGHPUT column in the WFC detector throughput tables was updated to match the extrapolation date. This ensures ETC calculations agree with pysynphot calculations that do not specify an MJD.
2024-09-09 hst_1180.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between April 17 and June 17, 2024. The files were generated from data taken in the same time frame under STIS calibration programs 17378 and 17376.
2024-09-09 hst_1179.pmap archived A recent analysis showed that the Lyman alpha gain sag holes on COS FUVB at LP5, which also appear at LP6, have gotten wider and are no longer being appropriately flagged. As such, a new COS GSAGTAB was delivered to account for these larger holes.
2024-09-05 hst_1178.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated follow the ACS WFC anneal on August 31, 2024, and should be used to calibrate ACS WFC observations taken between August 04, 2024 and August 31, 2024.
2024-08-22 hst_1177.pmap archived The new build of CalCOS applies a Y walk correction that is a function of YCORR rather than XCORR, as was previously the case. This means that the COS YWLKFILE must have dimensions 1024x32 instead of 16384x32. The COS YWLKFILE we are delivering here was previously delivered to crds-test as part of hst_1165.pmap, and used for regression testing, so we know this reference file works with the new build of CalCOS. In a few months, we will replace this COS YWLKFILE with a YWLKFILE that applies a correction that is dependent on the YCORR coordinate. This file affects all COS FUV data taken in TIME-TAG mode.
2024-08-21 hst_1176.pmap archived This new bad pixel table with USEAFTER of July 15, 2024 was generated using data taken from July 16, 2024, through August 13, 2024.

2024-07-29 hst_1170.pmap archived The new build of CalCOS, which is in the process of being installed into the operational pipeline, applies a sensitivity correction based on detector HV for the FUV. It, therefore, requires a COS HVDSTAB reference file that describes what this correction should be. Once the new CalCOS build is installed, the new keyword rules will set this file. However, the HVDSTAB we are delivering here is merely a DUMMY file that results in no actual correction. This file will eventually be replaced when the COS team finishes deriving all new FUV reference files as part of the post-walk/geo correction calibration effort. This file has already been delivered to CRDS-TEST and used for regression testing.
2024-07-24 hst_1169.pmap archived This new bad pixel table with USEAFTER of May 14, 2024 was generated using data taken from May 15, 2024, through June 15, 2024.

2024-07-12 hst_1167.pmap archived Delivering an initial rmap for new COS HVDSTAB reference file type.
2024-07-08 hst_1166.pmap archived Update to the COS NUV TDSTAB reference file for all modes, obtained using Python analysis scripts analyze_files.py, analysize_data.ipynb. A wavelength dependence was introduced to all supported modes and slopes were updated to model data up to August 2023. The file was tested by comparing all TDS observations since May 2009 to a reference model and by comparing NUV TA observations since September 2013 to remove sensitivity loss over time. The reference file has a USEAFTER date of 2009 May 11, the start of COS NUV operations.
2024-07-03 hst_1165.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from May 14, 2024 to June 14, 2024.

2024-07-01 hst_1164.pmap archived Updating TDSTAB reference files to reflect the latest time-dependent sensitivity trends for the NUVMAMA and CCD. For the NUVMAMA, new breakpoints were added at 01-01-2022 and 01-01-2024 to accommodate a drop in sensitivity--as low as 5 percent--between 1800 and 2100 angstroms. Due to uncertainty in how the NUVMAMA will behave after 01-01-2024, the slope after that time was made 0.0 in the 1600-1700 angstrom and 1800-2100 angstrom ranges until further data is available. All other NUVMAMA wavelength bins use the same slope after the 01-01-2024 breakpoint as the 01-01-2022 breakpoint. For the CCD, a new breakpoint was added at 01-01-2022 for only G230LB, G230MB, and MIRVIS to accommodate the same issue at the same wavelength range, 1800 to 2100 angstroms. The new CCD slopes post-2022 are extrapolated out for all wavelength bins.
2024-07-01 hst_1163.pmap archived A new ACS SBC IMPHTTAB is being delivered with updated data after newly acquired observations were taken on the 18th and 22th of Mar 2024 as part of CAL ACS program 17338.

2024-06-21 hst_1162.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between April 17 and June 17, 2024. The files were generated from data taken in the same time frame under STIS calibration programs 17377, 17378, and 17375.
2024-06-18 hst_1161.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on June 14, 2024, and should be used to calibrate ACS WFC observations taken between May 15, 2024 and June 14, 2024.
2024-06-07 hst_1160.pmap archived The STIS NUV-MAMA Dark Correction Table, or TDCTAB, encodes the scaling factor to be applied to the NUV-MAMA 2D DARKFILE as a function of MJD and detector temperature. Given additional monitoring datasets, we have refit the last bin in the previous TDCTAB and added two additional time bins, adopting a shared temperature linear slope within these time periods. Break points correspond to temporary increases in detector dark rate due to temperature fluctuations during instrument safing events and fits model the exponential decay of the dark rate. Data taken starting in late 2023 are not well characterized in this delivery and will be refit once additional dark monitoring data are available.
2024-06-03 hst_1159.pmap archived This new bad pixel table with USEAFTER of April 01, 2024 was generated using data taken from April 02, 2024, through May 14, 2024. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of March 09, 2024. The automated pipeline should now use this reference file as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because it represents the most accurate measure of pixel stability at the time of the science observation. These WFC3 UVIS bad pixel files were generated using 900 second dark exposures from the HST 31 daily monitoring programs 17345 and 17348. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
2024-06-03 hst_1158.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from April 1, 2024 to May 11, 2024. Currently, the automated calibration pipeline and CRDS have only WFC3 UVIS drk and dkc reference files with USEAFTER dates of up to March 28, 2024. The automated pipeline should now use these reference files to perform dark subtraction on any UVIS datasets obtained between the dates above, as they represent the most accurate picture of dark current and hot pixels for this time period. These WFC3 UVIS drk and dkc files were generated using dark exposures from HST Cycle 31 CAL programs 17345 and 17348.

2024-05-20 hst_1157.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on May 15, 2024, and should be used to calibrate ACS WFC observations taken between March 25, 2024 and May 15, 2024.
2024-05-15 hst_1156.pmap archived Since 2019, IR bad pixel tables and superdarks incorporate a new time dependence characteristic to the pixel quality for better calibration and flagging and tracking bad pixel behavior. These behaviors include hot and unstable pixels and whether any bad pixel has regained its stability since launch. Two new bad pixel tables are present here for data obtained through Cycles 29 and 30 with USEAFTER dates of November 29 2021 and November 05 2022, respectively. In addition, an error has been identified that overflags cold and unstable pixels in the current bad pixel table that uses cycle 28 data, 61s2016oibpx.fits. This error may affect the science of observations, and a new cycle 28 ir bad pixel table with the same USEAFTER of November 5 2020 that address and resolves this issue is presented here to replace 61s2016oibpx.fits. Information regarding pixel history and updates to the bad pixel table can be found in WFC3 ISRs 2019 03, 2019 04. Since launch, a litany of circular aberrant regions called blobs have appeared in IR images. These blobs are regions of lower sensitivity that appear due to bits of epoxy from the CSM motor shafts depositing onto the mirror. Tracking and flagging these blobs in the IR bad pixel table is therefore imperative so that they may be masked in any science images where they may appear. Information regarding blobs can be found in WFC3 ISR 2018 06. The two most recent blobs appeared on MJD 59378 and 59860. The existing table for the blob that appeared in MJD 59378, with a useafter of June 13 2021, uses Cycle 27 bad pixel data, though it appeared during Cycle 28. Likewise the existing table for the blob that appeared on 59860 MJD with a useafter of October 8 2022, uses Cycle 27 bad pixel data though they appeared during Cycle 29. These two bad pixel tables are being updated to reflect the bad pixel history concurrent with the appearance of the blob, such that the Cycle 28, useafter June 13 2021, blob contains Cycle 28 bad pixel data, and the Cycle 29 blob, useafter October 08 2022, blob contains Cycle 29 bad pixel data. In total, 5 bad pixel tables are being delivered, two new bad pad pixel tables using Cycle 29 and 30 data, and three new tables using Cycle 28 and 29 to replace the ones currently in CRDS. Additional information regarding these deliveries can be found in WFC3 ISR 2024 02.

2024-03-29 hst_1148.pmap archived New STIS NUVMAMA and CCD throughputs are being delivered for ETC version 32.2. Throughputs are updated due to changes in the NUVMAMA and CCD TDSTABs. There are no changes to the FUVMAMA throughputs, and these files are evaluated to match the MJD evaluation date of ETC version 32.2.
2024-03-28 hst_1147.pmap archived Updated COS FUV synphot files for ETC 32.2. These include throughput changes due to updating the FUV FLUXTAB and TDSTAB. No NUV updates at this time. These are evaluated at MJD 60766.
2024-03-19 hst_1146.pmap archived Update to the COS FUV TDSTAB and FLUXTAB reference files for all modes, obtained using python analysis scripts cos_tds_analysis.py, make_tds_reference.py. A new breakpoint was introduced at 2023.2 and slopes were updated to model data up to January 2024. The file was tested by comparing all TDS observations since SM4 to a reference model. The TDSTAB file needs to be used with the new FLUXTABs for LP2, LP3, LP4, LP5, and LP6 which have sensitivities backed out using the updated TDS parameters, and which were delivered on the same date. These reference files have a USEAFTER date of 2017 October 2, the start of routine operations at LP4.
2024-03-19 hst_1145.pmap archived These new 2023 WFC3 UVIS postflash files were created in the same manner as detailed in WFC3 ISR 2023-01 for postflashed UVIS data taken in 2023.

2024-03-08 hst_1141.pmap archived Deleting the synphot througput file roman_wfi_w146_002_syn.fits to prepare for the delivery of a replacement file, that will use the element name F146 instead.
2024-02-19 hst_1140.pmap archived A new post-flash reference file, FLSHFILE, is being delivered because new post-flash calibration data was taken in Nov 2023 as part of proposal 17343. The raw darks were separated by EXPTIME and FLASHDUR and combined with ACSREJ to create short and long-flashed superdarks. These superdarks were differenced and scaled to create an intermediate data product that was then smoothed with a local median filter and renormalized to produce the final post-flash reference file. This reference file is to be used in the calibration of post-flashed data taken after July 01 2023.

2024-02-12 hst_1138.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between December 22, 2023 and January 24, 2024. The files were generated from data taken in the same time frame under STIS calibration programs 17377 and 17374. Week 02 reference files were skipped due to instrument safings, as they spanned the safing events and did not correspond to any STIS science datasets. Only one gain 4 bias is available as well.
2024-01-30 hst_1137.pmap archived These two new bad pixel tables with USEAFTERs of October 24, 2023, and December 07, 2023 were generated using data taken from October 25, 2023, through January 07, 2024. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of September 26, 2023. The automated pipeline should now use these reference files as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because they represent the most accurate measure of pixel stability at the time of the science observation. These WFC3 UVIS bad pixel files were generated using 900 second dark exposures from the HST 30 daily monitoring programs 16967 and 17005 as well as cycle 31 programs 17345 and 17347. These two bad pixel tables were created using darks calibrated with the yearly postflash file. See WFC3 ISR 2023.01 for information about yearly postflash files. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
2024-01-24 hst_1136.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from July 9, 2023, to December 7, 2023.

2024-01-04 hst_1134.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between November 16 and December 22 2023. The files were generated from data taken in the same time frame under STIS calibration programs 17377 and 17374. Fewer gain 4 bias reads than typical are available due to instrument safings, giving an elevated noise level in the gain 4 superbias. However, this file is not used by any science observations within this annealing period. The sole superdark and gain 1 superbias were expanded slightly to encompass all reads.
2024-01-04 hst_1133.pmap archived For COS NUV G230L, cenwave 2635, exposure lev0l2geq, the planned exposure time was 540 s. However, the target began to drift out of the aperture after 155 s, and the counts dropped to 0 by 162 s. This update to the COS BADTTAB excludes the period beginning on that day at 13h09m07s, 154.1 s into the exposure and just before the target was lost, and ending at 13h19m07s, just before the next exposure began, when the target was back in the aperture.
2023-12-22 hst_1132.pmap archived In the most recent delivery of WFC3 UVIS darks, there was a slight mismatch in USEAFTERs that caused two old files to not be replaced. We are removing 6aa1643ai_drk.fits and 6aa1641ei_dkc.fits from the rmap so that the new correct files will be used instead.

2023-10-25 hst_1106.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between September 22 2023 and October 19 2023. The files were generated from data taken in the same time frame under STIS calibration programs 16950 and 16948.
2023-10-25 hst_1105.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from July 18, 2013, to March 25, 2014. These drk and dkc reference files were generated using dark exposures from HST programs 13071, 13076, 13554, 13556, and 13557. These files will replace existing references. The automated pipeline shoud now use these reference files to perform dark subtraction for any UVIS datasets obtained between the dates above, as they have been reprocessed using a new time-dependent post-flash calibration, outlined in WFC3 ISR 2023-01, and represent the most accurate picture of dark current and hot pixels for data using this new calibration. The header of each reference file contains a detailed history section outlining the process and data used to create each file. More information on the process can be found in WFC3 ISR 2016-08.

2023-10-16 hst_1103.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on October 11, 2023, and should be used to calibrate ACS WFC observations taken between September 17, 2023 and October 11, 2023.
2023-10-11 hst_1102.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between August 25 2023 and September 22 2023. The files were generated from data taken in the same time frame under STIS calibration programs 16950 and 16948. The CCD housing temperature fluctuated more than typical during this annealing period due to a STIS safing event. To compensate for this, weekdarks were derived from temperature-filtered data to better match science observations taken in the same time period.
2023-09-19 hst_1101.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on September 17, 2023, and should be used to calibrate ACS WFC observations taken between August 15, 2023 and September 17, 2023.
2023-09-18 hst_1100.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between July 27 2023 and August 25 2023. The files were generated from data taken in the same time frame under STIS calibration programs 16950 and 16948. The CCD housing temperature fluctuated this more than typical this annealing period due to two STIS safing events. To compensate for this, the third gain 1 weekdark was derived from temperature-filtered data to better match science observations taken in the same time period.
2023-08-21 hst_1099.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on August 15, 2023, and should be used to calibrate ACS WFC observations taken between July 19, 2023 and August 15, 2023.

2023-08-16 hst_1097.pmap archived Update to the COS FUV TDSTAB and FLUXTAB reference files for all modes. New breakpoints were introduced at 2020.6 and 2022.0 and slopes were updated to model data up to March 2023. The file was tested by comparing all TDS observations since SM4 to a reference model. The TDSTAB file needs to be used with the new FLUXTABs for LP2, LP3, LP4, LP5, and LP6 which have sensitivities backed out using the updated TDS parameters, and which were delivered on the same date. These reference files have a USEAFTER date of 2017 October 2, the start of routine operations at LP4.
2023-08-15 hst_1096.pmap archived Delivering updated darkfile and drkcfile rmaps following the delivery of new ACS WFC darks and CTE-darks. The new dark reference files use CCDGAIN = -1, which expands to gain values of 0.5, 1.0, 1.4, 2.0, 4.0, and 8.0 upon ingestion into CRDS. The existing rmaps had these gain values for post-2015 entries, but were different for pre-2015 entries, resulting in the old pre-2015 reference files not being replaced properly. We have removed the files that should have been replaced and use the correct set of gain values in these updated rmaps.
2023-08-15 hst_1095.pmap archived These new ACS WFC dark and CTE-corrected dark reference files, affecting both pre- and post-SM4 data, are being delivered because of several improvements to the ACS Reference File Pipeline. As detailed in ACS ISR 2022-07, very hot pixels, those with dark current greater than 20 e-/s, do not accumulate dark current at a constant rate over the course of an exposure. These pixels are known as fading hot pixels, and are least likely to be properly dark-corrected with CALACS. Therefore, the pipeline was updated to flag these pixels with DQ flag 32 in the dark reference files to deem them unusable for science purposes. Saturated pixels, A-to-D and full-well, are now also being flagged in the dark reference files with DQ flag 512. Post-2015 superdarks had an exposure time issue where the EXPTIME used for normalization was 999.4842s, not 999.9921s as it should have been. The EXPTIME has since been corrected and implemented in these new superdarks. Finally, the pipeline was updated to set FIXROCR in the local PCTETAB to zero after it was concluded that this extra step in the CTE correction algorithm was not needed when stacking several darks together, which is the process when creating dark reference files in the reference file pipeline.
2023-08-15 hst_1094.pmap archived One ACS WFC darkfile, 78f18166j_drk.fits, was ingested with the wrong useafter date and did not replace the old darkfile as intended. Deleting this file and delivering the corrected version with the next batch of darks.

Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of October 24, 2022. The automated pipeline should now use this reference file as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because they represent the most accurate measure of pixel stability at the time of the science observation. These WFC3 UVIS bad pixel files were generated using 900 second dark exposures from the HST 30 daily monitoring programs 16967, 17003, and 17004.

2023-07-26 hst_1089.pmap archived Processing of recent SBC data has been skipping PHOTCORR, which populates photometry keywords in the header. The reason is the SBC IMPHTTAB does not provide photometry information past MJD 60035. New SBC time-dependent sensitivity, TDS, throughput tables were delivered for all SBC filters and prisms that extrapolate out to MJD 60401. Now that a new component table, TMC, is available, an updated SBC IMPHTTAB has been generated to fix the issue with PHOTCORR being skipped.

2023-06-30 hst_1080.pmap archived The previous LP6 XTRACTAB and TWOZXTAB reference files had a background region defined such that a source could contaminate it should it happen to fall inside the BOA, potentially resulting in bad background subtraction. We moved this background region, which resulted in very small tweaks to the TRCETAB and PROFTAB files.
2023-06-28 hst_1079.pmap archived New STIS NUVMAMA Synphot throughput files delivered to support the ETC 31.2 release. The underlying time dependent sensitivity, TDS, file was updated with recent STIS monitoring data from program 16960. This TDS file will be delivered to CRDS in the next few weeks.

The process of creating these time dependent reference files are described in detail in WFC3 ISR 2023 01. Currently the pipeline uses the 2021 post-flash reference files on data taken in 2022 and 2023, this update will apply the post-flash reference file from 2022 to that data instead. They were made from Cycle 29 and 30 from proposals 16570 and 16982.
2023-04-19 hst_1073.pmap archived These WFC3 UVIS superbias, bia, files will affect all full-frame and subarray 1x1 binned UVIS data. The 2021 superbiases will affect data taken from January 1 - December 31 2021. The 2022 superbiases will affect all data taken after January 1, 2022. Currently, the automated calibration pipeline and Calibration Reference Data System only have WFC3 UVIS full-frame and subarray bias reference files up to a USEAFTER date of January 1, 2020. The automated pipeline should now use these reference files to perform bias subtraction on any 1x1 binned UVIS datasets obtained between the dates above because they represent the most accurate estimate of the residual bias level at the time of the science observation. The 2021 WFC3 UVIS superbias files were generated using bias exposures from the HST Cycle 28 and 29 monitoring programs 16414 and 16564. The 2022 WFC3 UVIS superbias files were generated using bias exposures from the HST Cycle 29 and 30 monitoring programs 16414 and 16967. More information regarding the method used to create UVIS bias calibration reference files can be found in I.Rivera, B.Kuhn, 2023. Additionally, the header of each reference file has a history section listing the datasets used to create each file.

2023-02-22 hst_1067.pmap archived A new postflash reference file, FLSHFILE, is being delivered because new post-flash calibration data was taken in Nov 2022 as part of proposal 16980. The raw darks were separated by EXPTIME and FLASHDUR and combined with ACSREJ to create short and long-flashed superdarks. These superdarks were differenced and scaled to create an intermediate data product that was then smoothed with a local median filter and renormalized to produce the final postflash file.
2023-02-22 hst_1066.pmap archived These new ACS WFC CCDTABs are being delivered because ACS ISR 2023-01 showed that no corrections are needed to commanding overheads in DARKTIME. These corrections are located in the OVRHFLS and OVRHUFLS columns of the CCDTABs, and are now set to zero.
2023-02-16 hst_1065.pmap archived These STIS CCD superbias and superdark files are being delivered to ensure that STIS CCD data taken between January 11 2023 and February 9 2023 are properly corrected for the effects of bias noise and dark current.

2023-01-12 hst_1061.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Jan 07, 2023, and should be used to calibrate ACS WFC observations taken between Dec 10, 2022 and Jan 07, 2023.
2023-01-12 hst_1060.pmap archived A growing number of small, circular regions with slightly decreased sensitivity have appeared in WFC3 IR images throughout the mission. As described in Pirzkal et al. 2010, these so called IR blobs appear due to particulates on the channel select mechanism CSM, the movable mirror that is used to direct light into the IR channel. These particulates are likely cracked epoxy originating from two pins joining the CSM motor shafts to the alignment bellows, therefore, it is critical that blob accumulation is monitored as a growing number of blobs may signify a loosening of these pins, and thus a defective CSM. A new IR bad pixel table delivery must be done if there is a new blob found with relative strength that matches previously flagged blobs. As such, this bad pixel table adds a record of a new blob, number 153, that appeared sometime after the USEAFTER date in the primary header of this file, Oct 08 2022. For further information on the blobs origins, characteristics, and the WFC3 blob monitoring techniques, see WFC3 ISR 2018 06.

2022-12-12 hst_1055.pmap archived New ACS WFC synphot throughput files have been created to update the default THROUGHPUT column to the extrapolation date of ETC 31.1., MJD 60401. This ensures ETC calculations agree with pysynphot calculations that do not specify an MJD.
2022-12-12 hst_1054.pmap archived New STIS throughputs are being delivered to update the synphot default MJD evaluation date, matching ETC version 31.1.
2022-12-08 hst_1053.pmap archived These new WFC3 UVIS postflash reference files, described in detail in WFC3 ISR 2022 09, incorporate a time dependence in order to better calibrate data that has been postflashed. Previously a single reference file was used for all data while taking into account shutter and lamp current, but this has been found to be inaccurate due to changes in the detector sensitivity over time. Now reference files are created from all postflash dark images from a single calendar year, except 2012 which uses some overlap from 2013 to allow a full dataset. These new reference files have been found to better remove postflash applied to data than the previous reference files.
2022-12-07 hst_1052.pmap archived This new bad pixel table, USEAFTER October 24, 2022, was generated using data taken from October 25, 2022 through November 26, 2022. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of September 29, 2022. The automated pipeline should now use this reference file as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because they represent the most accurate measure of pixel stability at the time of the science observation. This WFC3 UVIS bad pixel file was generated using 900 second dark exposures from the HST Cycle 29 and 30 daily monitoring programs 16564, 16568, 16967, and 17003. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.

2022-11-17 hst_1049.pmap archived These ACS WFC dark and CTE-corrected dark reference files are older versions of files currently in CRDS and need to be deleted from the rmap. These old files must have not been replaced correctly in the last large dark delivery in 2020 due to the CCDGAIN values of -1 expanding to slightly different values -- 0.5, 1.0, 1.4, 2.0, 4.0, 8.0 in new files and 0.5, 1.0, 1.4, 2.0 in old files. The correct expansion going forward is the new one, so the old files must be deleted to reflect this.

2022-09-15 hst_1038.pmap archived A new hot spot was discovered on the COS FUV Segment A detector while examining recent dark monitor data. Since the hot spot falls in a part of the detector that overlaps with the extraction region of science spectra taken at lifetime position 4, it was important to identify all exposures where the hot spot added a significant enough number of counts to affect the observations. These time periods were identified manually and then added to the SPOTTAB file. As a result, reprocessing of these files should completely remove the hot spot counts.
2022-09-15 hst_1037.pmap archived The COS NUV XTRACTAB background regions were too close to the PSA extraction regions. In some cases, this led to the wings of the PSA to be subtracted during the 1-D spectral extraction process, resulting in a lower flux being reported in the NUV. The updated NUV XTRACTAB moves the background extraction regions closer to the edges of the detector. This prevents over-subtraction from the PSA spectra and gives consistent flux values between the NUV and FUV arms.
2022-09-13 hst_1036.pmap archived The CENWAVE keyword automatically populated UNDEFINED instead of N/A for the new LP6 file 69d21090l_flat.fits delivered on 2022 09 13. This delivery fixes it to N/A which matches the other files specified in the rmap.

2022-04-07 hst_1003.pmap archived The STIS team is delivering a new set of PHOTTAB and RIPTAB files built upon the latest CALSPECv11 models released in 2020. These new files improve the accuracy of several STIS spectroscopic modes, including G140L, G230L, E140M, G230LB, and G430L. This delivery is the first of four eventual data releases and targets what were determined to be the highest impact modes for the user community.
2022-04-06 hst_1002.pmap archived A new ACS SBC IMPHTTAB is being delivered with updated data after newly acquired observations were taken on 20 Mar 2022 as part of CAL/ACS program 16527.
2022-04-05 hst_1001.pmap archived In preparation for ETC 30.2, the synphot throughput files for all COS FUV and NUV cenwaves - except from the unsupported NUV grating G285M - were updated based on an updated flux calibration. This new calibration resulted from new white dwarf spectral models. While some of these modes, e.g. G140L cenwave 800, already have the most recent flux calibration incorporated into their throughputs, all files are being delivered to both make sure all files have the up-to-date default MJD and standardize the delivery process.
2022-04-01 hst_1000.pmap archived New ACS SBC TDS throughput files need to be delivered for the upcoming ETC build. Aiming to include these files in ETC 30.2.
2022-04-01 hst_0999.pmap archived The ACS WFC bias, dark, CTE dark, and sink files for the 2022-02-05 anneal period are being redelivered after it was discovered that the original files excluded valid calibration frames taken on 2022-02-28. These new references now include the missing calibration frames, and will replace the previous versions in CRDS.
2022-04-01 hst_0998.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Mar 28, 2022, and should be used to calibrate ACS WFC observations taken between Feb 28, 2022 and Mar 28, 2022.
2022-03-31 hst_0997.pmap archived This new bad pixel table, USEAFTER Feb 19, 2022, was generated using data taken from Feb 20, 2022 through March 15, 2022. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of Jan 18, 2022. The automated pipeline should now use this reference file as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because it represents the most accurate measure of pixel stability at the time of the science observation. This WFC3 UVIS bad pixel table was generated using 900 second dark exposures from the HST Cycle 29 daily monitoring programs 16564, and 16566. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
2022-03-30 hst_0996.pmap archived These WFC3 UVIS superdarks and CTE-corrected superdarks will affect all UVIS data taken from January 18, 2022, to February 17, 2022. Currently, the automated calibration pipeline and CRDS have only WFC3 UVIS drk and dkc reference files with USEAFTER dates of up to January 15, 2021. The automated pipeline should now use these reference files to perform dark subtraction on any UVIS datasets obtained between the dates above, as they represent the most accurate picture of dark current and hot pixels for this range. These WFC3 UVIS drk and dkc files were generated using dark exposures from HST Cycle 29 daily monitor programs 16564 and 16566. More information regarding the method used to create the UVIS dark calibration reference files can be found in WFC3 ISR 2016-08.

2022-03-29 hst_0995.pmap archived The wavelength range for Pysynphot in the STIS CCD G750M c9851 mode was updated to correct a typo on the red end. This will be used in ETC 30.2.
2022-03-28 hst_0994.pmap archived After updates to the crds code were installed to ensure the proper ACS biasfile selection for pre-SM4 subarray datasets and to implement the switch to selecting on RAW_LTV1 and RAW_LTV2 instead of LTV1 and LTV2 keywords, a new bias rmap delivery is necessary. This new rmap uses version 3 of the fallback and precondition hooks as well as parkeys RAW_LTV1 and RAW_LTV2. The rmap also adds values of WFC and WFC1 to entries using the ANY_WFC1_2K aperture wildcard and WFC2 to entries using the ANY_WFC2_2K aperture wildcard, values that should now automatically be populated with the updated code. See CRDS-500 for more information on the initial selection issues.
2022-03-28 hst_0993.pmap archived Five ACS WFC biasfiles were not replaced in the most recent delivery because of an extra aperture value of WFC that was previously added to the aperture list. Deleting the old references that were not replaced, given that the aperture values will be appropriately updated in a future rmap delivery after updates to the crds servers are implemented.
2022-03-25 hst_0992.pmap archived Several ACS WFC biasfiles using CCDGAIN=1 were not replaced in the most recent delivery because of an extra aperture value of WFC that was previously added to the aperture list. Deleting the old references that were not replaced, given that the aperture values will be appropriately updated in a future rmap delivery after updates to the crds servers are implemented.
2022-03-25 hst_0991.pmap archived Delivering new WFC pre-SM4 subarray bias files for configurations using CCDAMPs A and B, to fix the EXTVER keyword values that will result in reprocessing errors for data using these references. The EXTVER values in all extensions were mistakenly set to 2 in the initial creation of the files, but are being updated to have EXTVER values of 1. Several files were previously fixed for this issue in hst_0948.pmap and hst_0951.pmap. This delivery precedes updates to the ACS BIASFILE selection rules to mitigate any potential reprocessing errors that may follow.
2022-03-25 hst_0990.pmap archived A misalignment was found between cenwaves 2950 and 2635 for COS G230L. This new DISPTAB updates the dispersion solution to correctly align cenwaves 2635, 2950, and 3000.
2022-03-15 hst_0989.pmap archived Regular delivery of STIS CCD superdarks and superbiases needed to support the calibration of STIS CCD data taken from February 8th to March 14th 2022.
2022-03-03 hst_0988.pmap archived Intrinsic excess thermal energy trapped in the silicon lattice of the WFC3 UVIS detector, known as dark current, is typically removed from science observations using UVIS dark calibration reference files. This dark current can be used as a means to characterize a pixels behavior and determine whether the pixel varies excessively over time compared to its expected noise. We use a novel data structure known as a pixel history image to efficiently evaluate each WFC3 UVIS pixel over time. We find that the vast majority of hot pixels, about 8 percent of the detector in 2021, are in fact quite stable and as such, can be calibrated. A small portion of pixels, less than 1.5 percent, are genuinely unstable and should not be used. To encode this distinction in the UVIS bad pixel reference files, we employ a data quality flag, 32, to mark the unstable pixels identified in this study. Hot pixels continue to be assigned the usual data quality flag, 16. With the additional data quality flag, WFC3 UVIS users will have enhanced control over which pixels to include or exclude during their analyses. The first new bad pixel table was generated using data taken from December 21st, 2021 through January 18th, 2022. The second new bad pixel table was generated using data taken between January 19th, 2022 and February 19th, 2022. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of November 22nd, 2021. The automated pipeline should now use these reference files as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because they represent the most accurate measure of pixel stability at the time of the science observation. These WFC3 UVIS bpx files were generated using 900 second dark exposures from the HST Cycle 28 daily monitoring programs 16414 and 16396. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
2022-03-03 hst_0987.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Feb 28, 2022, and should be used to calibrate ACS WFC observations taken between Feb 05, 2022 and Feb 28, 2022.
2022-03-03 hst_0986.pmap archived Updates to the COS WCPTAB and FLATFILE rmaps. The WCPTAB rmap was updated to include LIFE_ADJ=-1.0 and the FLATFILE rmap was updated to set CENWAVE from UNDEFINED to N/A for the G160M LP6 flatfile reference.
2022-03-03 hst_0985.pmap archived Copying reference files from TEST to OPS servers. The lamp and profile references are place holders so that LP6 calibrations will not fail. In order to process COS FUV LP6 data, the preliminary LP6 reference files are being updated to remove their unnecessary BOA rows. Additionally an LP4 flatfile was copied and its LIFE_ADJ changed from 4 to 6, so that it could be used as an initial LP6 flatfile.
2022-03-03 hst_0984.pmap archived Re-activating COS FLUXTAB reference files originally delivered on February 22, 2022. The CALSPEC model spectra for several standard stars were improved in early 2021, which included those for WD0308-565 and GD71. As a result, the COS/FUV sensitivity curves, found within the FLUXTAB reference files, for lifetime positions 1 through 4 needed to have a correction applied so that the data would be consistent with CALSPEC. The source flux ratio between the old and new models was used to scale the existing sensitivities to the current CALSPEC model. The delivery had to be backed out when it was discovered that the new reference files were not compatible with the current version of the COS claibration software.
2022-03-01 hst_0983.pmap archived Previously, the ACS WFC BIASFILE reference 5851837rj_bia.fits was updated in the rmap to have a USEAFTER of Jul 06 2009 16-58-18 to cover previously missed datasets. This file was never redelivered with updated header information to reflect this change, so we are redelivering this file with updated USEAFTER and DESCRIP keywords to be consistent.
2022-02-22 hst_0982.pmap archived The CALSPEC model spectra for several standard stars were improved in early 2021. This included WD0308-565 and GD71, which were updated to Model 006 and Model 011 respectively. Due to this, the COS/FUV sensitivity curves, found within the FLUXTAB reference files, for lifetime positions 1 through 4 needed to have a correction applied so that the data would be consistent with CALSPEC. The source flux ratio between the old and new models was used to scale the existing sensitivities to the current CALSPEC model.
2022-02-18 hst_0981.pmap archived New weekly STIS biases and darks were created for the last two anneal months and need to be delivered for GO observations. These files are available from STIS CCD observations taken after December 7 2021 21 09 22.

2022-02-11 hst_0978.pmap archived This ACS WFC Post-Flash reference file is being delivered because new calibration data was taken in Nov 2021 as part of proposal 16532. This particular reference file is updated yearly.
2022-02-08 hst_0977.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Feb 05, 2022, and should be used to calibrate ACS WFC observations taken between Jan 07, 2022 and Feb 05, 2022.
2022-01-28 hst_0976.pmap archived Since 2019, IR bad pixel tables and superdarks incorporate a new time dependence characteristic to the pixel quality for better calibration and flagging and tracking bad pixel behavior. These behaviors include hot and unstable pixels and whether any bad pixel has regained its stability since launch. One new bad pixel tables is present here for data obtained through Cycle 28 which uses inflight data from Nov. 5 2020 through Oct. 21 2021 with a useafter date of Nov. 5 2020. The Calibration Reference Data System does not contain bad pixel tables spanning this baseline. Information regarding pixel history and updates to the bad pixel table can be found in WFC3 ISRs 2019.03 and 2019.04. Since launch, a litany of circular aberrant regions called blobs have appeared in IR images. These blobs are regions of lower sensitivity that appear due to bits of epoxy from the CSM motor shafts depositing onto the mirror. Tracking and flagging these blobs in the IR bad pixel table is therefore imperative so that they may be masked in any science images where they may appear. Information regarding blobs can be found in WFC3 ISR 2018.06. The cycle 28 bad pixel table includes a blob that appeared on MJD 59378, 06.13.2021.

2021-11-19 hst_0968.pmap archived These ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Nov 10, 2021. Due to HST safing on Oct 23, 2021, calibration frames for the Oct 11, 2021 anneal period were split between pre- and post-safing. ACS returned to science operations on Nov 07, 2021, but the WFC detector had warmed up during this time. Because of this, superdarks using calibration frames from pre- and post-safe were exhibiting a large increase in unstable pixels due to post-safe darks having different dark current levels and hot pixel characteristics than pre-safe darks. To best calibrate science data taken during this anneal period, we create two separate sets of reference files - one for data taken before the CCD warm up, and one for data taken after ACS returned to science, but prior to the anneal on Nov 10, 2021. The first set of references should be used to calibrate ACS WFC observations taken between Oct 11, 2021 and Nov 07, 2021, and the second set with data taken between Nov 07, 2021 and Nov 10, 2021.
2021-11-09 hst_0967.pmap archived Several COS reference files - with filetypes fluxtab,gsagtab,lamptab,1dxtab,tracetab,lamptab,2zxtab,proftab,disptab,bpixtab - were delivered with empty data extensions in their primary fits header because of a minor bug in the CRDS checksum code. While the data contained in the files is correct, this empty header could cause issues for some scripts which do not specify the data header number. These files are being replaced with versions which lack the empty data extension but are otherwise identical. No data has been changed.
2021-11-09 hst_0966.pmap archived A recent analysis by the ULLYSES team revealed a hot spot in a small but non-negligible fraction of their COS FUVB data. We verified that the hot spot started on Feb. 20, 2018 and persists intermittently today. The hot spot falls in one of the background regions used for LP4 FUVB data reduction, and can negatively impact background-limited target data. The delivered spottab file removes this hot spot region so that CalCOS does not include it in the background calculation for observations taking place on or after Feb. 20, 2018.
2021-11-04 hst_0965.pmap archived The first post-SM4 ACS WFC superbias covering subarray configurations using amplifier A and aperture WFC1-IRAMPQ, 5851837rj_bia.fits, previously needed its USEAFTER date backdated to 2009-07-20 00-00-00 to cover observations using this same configuration before the first calibration biases were taken post-SM4. We are now further backdating the USEAFTER date of 5851837rj_bia.fits to 2009-07-06 16-58-18 to be consistent with similar subarray superbias files that had their USEAFTER dates backdated for the same reason.

2021-09-30 hst_0957.pmap archived Because of 2020 rule changes, new flatfiles delivered need to include the header keyword CENWAVE, usually but not always set to N/A. A flatfile, 5992009ql_flat.fits, was delivered without this keyword and was assigned an UNDEFINED CENWAVE value by CRDS in the flatfile rmap. We are manually changing this UNDEFINED value to the expected N/A value so that this flatfile applies to all COS/FUV LP5 files, regardless of CENWAVE.

More information regarding the method used to create UVIS dark calibration reference files can be found in WFC3 ISR 2016 08. Additionally, the header of each reference file has a detailed history section outlining the process and provides a list of datasets used to create each file.
2021-09-24 hst_0955.pmap archived New weekly biases and darks were created for the new anneal month and need to be delivered for GO observations. These files are available from STIS CCD observations taken after Aug 19 2021.
2021-09-21 hst_0954.pmap archived Updating the reference files to avoid extrapolation from 2014 to present. The new IMPHTTAB serves post-SM4 data in place of the previous IMPHTTAB, which is now only valid for pre-SM4 data.
2021-09-17 hst_0953.pmap archived Intrinsic excess thermal energy trapped in the silicon lattice of the WFC3 UVIS detector, known as dark current, is typically removed from science observations using UVIS dark calibration reference files. This dark current can be used as a means to characterize a pixels behavior and determine whether the pixel varies excessively over time compared to its expected noise. We use a novel data structure known as a pixel history image to efficiently evaluate each WFC3 UVIS pixel over time. We find that the vast majority of hot pixels, about 8 percent of the detector in 2021, are in fact quite stable and as such, can be calibrated. A small portion of pixels, less than 1.5 percent, are genuinely unstable and should not be used. To encode this distinction in the UVIS bad pixel reference files, we employ a data quality flag, 32, to mark the unstable pixels identified in this study. Hot pixels continue to be assigned the usual data quality flag, 16. With the additional data quality flag, WFC3 UVIS users will have enhanced control over which pixels to include or exclude during their analyses. These new bad pixel tables were generated using data taken from October 29th, 2020 through September 8th, 2021. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of October 28th, 2020. The automated pipeline should now use these reference files as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond, because they represent the most accurate measure of pixel stability at the time of the science observation. These WFC3 UVIS bpx files were generated using 900 second dark exposures from the HST Cycle 27 and 28 daily monitoring programs 15712, 15716, 16414, 16394, 16395, and 16396. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
2021-09-16 hst_0952.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Sep 13, 2021, and should be used to calibrate ACS WFC observations taken between Aug 22, 2021 and Sep 13, 2021.
2021-09-16 hst_0951.pmap archived An ACS WFC dataset, jb6e80010, was failing in-cloud reprocessing due to incorrect EXTVER header keyword values in the SCI, ERR, and DQ extensions. The file had EXTVER keyword values of 2 instead of the expected 1 and thus were causing CALACS HST I/O errors. A new BIASFILE was created with updated EXTVER values to fix this problem.
2021-09-16 hst_0950.pmap archived In discovering that an ACS WFC dataset, jb6e80010, failed in-cloud reprocessing, we also discovered that this dataset was being matched with the incorrect BIASFILE in CRDS. It turns out that an appropriate, post-SM4 BIASFILE for CCDAMP A and APERTURE WFC1-IRAMPQ subarrays did not exist in CRDS to cover this dataset. To remedy this, we extend the USEAFTER date of the closest BIASFILE with this subarray configuration, 5851837rj_bia.fits, to 2009-07-20 to account for this dataset. We are delivering a new ACS BIASFILE rmap to reflect this update.
2021-09-15 hst_0949.pmap archived Remove rmap_omit from synphot mappings, which was incorrectly specified and caused warnings when recommending synphot references.
2021-09-13 hst_0948.pmap archived Several ACS datasets were failing in-cloud reprocessing due to eight ACS/WFC WFC1-1K subarray BIASFILEs that had incorrect EXTVER header keyword values. The files had EXTVER keyword values of 2 instead of the expected 1 and thus were causing CALACS HST I/O errors. New BIASFILEs were created with the EXTVER keyword set to 1 in the SCI, ERR, and DQ extensions to fix this problem.
2021-09-09 hst_0947.pmap archived In preparation for the COS FUV LP 5 era, we needed to update the COS FUV BPIXTAB reference file to search for new low, DQ=1024, and very low, DQ=16, response regions in the LP5 area of the detector. In addition, we took the opportunity to remove or resize existing regions in the BPIXTAB that were found be invalid. This new file has added 11 new low response regions, DQ=1024, and no new very low response regions, DQ=16. We also removed 3 regions, for a net gain of 8.
2021-09-09 hst_0946.pmap archived Beginning in October 2021, limetime position 3 LP3 will become the default LP for G140L 1105,1280,800 modes. These seven reference files are updates to the existing LP3 reference files to now calibrate cenwave 800 which was originally commissioned at LP4, and thus did not have optimal calibration at LP3.
2021-09-09 hst_0945.pmap archived Beginning in October 2021, limetime position 5, LP5, will become the default LP for G130M 1291,1300,1309,1318,1327 modes. These eight reference files provide optimally calibrated data at that LP and enable TWOZONE extraction at LP5.
2021-09-09 hst_0944.pmap archived Two LP4 FLUXTAB reference files for LP4 are necessary with USEAFTER dates matching the two TDSTAB reference files currently in use. Previously, LP4 calibration data obtained prior to the official move to LP4 in October 2017 used a FLUXTAB and TDSTAB with mismatched zero points and therefore had incorrect fluxes, and should be re-retrieved.
2021-08-25 hst_0943.pmap archived New weekly biases and darks were created for the new anneal month and need to be delivered for GO observations. These files are available from STIS CCD observations taken after July 27 2021 23 00 00.

2021-08-12 hst_0940.pmap archived New weekly biases and darks were created for the new anneal month and need to be delivered for GO observations. These files are available for STIS CCD observations taken after May 5 2021. Anneal periods for June and July 2021 are shorter than typical due to HST safing events, so noise is slightly elevated.
2021-08-06 hst_0939.pmap archived After the delivery of ACS WFC post-SM4 subarray superbias files, two files from 2016 were not replaced with the appropriate new file. Because of this, the rmap needed to be updated to delete the old entries from the rmap.
2021-08-05 hst_0938.pmap archived Updates to the variance and read noise calculations for subarrays in the readout dark code used in the reference file pipeline required that all ACS WFC subarray superbias files be remade. Since pre-SM4 subarray superbias files did not already exist in CRDS, subarray science data taken during this time period was identified and subarray superbias files were produced only for the necessary anneal periods and subarray configurations. Updated versions of the full-frame, pre-SM4 superbiases for the affected anneals are also being delivered to keep things consistent. For post-SM4 data, the existing subarray superbiases in CRDS are being replaced with updated files.
2021-08-05 hst_0937.pmap archived Following the most recent delivery of ACS WFC pre-SM4 subarray bias files, some of the files needed APERTURE values of WFC or WFC2 in addition to the wildcard APERTURE keywords of ANY_WFC1_2K or ANY_WFC2_2K in their headers. However, CRDS would not allow this upon submission, so these additional APERTURE values had to be manually added to the applicable entries in the rmap.

2021-08-04 hst_0935.pmap archived The previous delivery of ACS WFC full-frame superbias files was supposed to replace a subset of superbias files currently in CRDS, but were added to the rmap in addition to the old ones instead. We are deleting the old references, because these new files have a more accurate CCDAMP keyword in preparation for the delivery of brand new pre-SM4 subarray superbias files.
2021-08-04 hst_0934.pmap archived Updates to the variance and read noise calculations for subarrays in the readout dark code used in the reference file pipeline required that all ACS WFC subarray superbias files be remade.

2021-07-22 hst_0933.pmap archived A growing number of small, circular regions with slightly decreased sensitivity have appeared in WFC3 IR images throughout the mission. As described in Pirzkal et al. 2010, these so called IR blobs appear due to particulates on the channel select mechanism CSM, the movable mirror that is used to direct light into either the UVIS or IR channels of the instrument. These particulates are likely cracked epoxy originating from two pins joining the CSM motor shafts to the alignment bellows, therefore, it is critical that blob accumulation is monitored as a growing number of blobs may signify a loosening of these pins, and thus a defective CSM. A new IR bad pixel table delivery must be done if there is a new blob found with relative strength that matches previously flagged blobs. As such, this bad pixel table adds a record of a new blob that has appeared sometime after the USEAFTER date in the primary header of this file. For further information on the blobs origins, characteristics, and the WFC3 branchs blob monitoring techniques, see WFC3 ISR 2018 06.

2021-07-16 hst_0931.pmap archived This reference file is for the COS instrument for use in the NUV configuration. It was generated to update NUV DQ flag 2 to flag 1024 to reflect changes made in 2014 to change DQ flag of 2 from detector flaw to a low response region. This flag was updated in the FUV, but never in the NUV.

2021-03-05 hst_0865.pmap archived Since 2019, IR bad pixel tables and superdarks incorporate a new time-dependence characteristic to the pixel quality for better calibration and flagging and tracking bad pixel behavior. These behaviors include hot and unstable pixels and whether any bad pixel has regained its stability since launch. Two bad pixel tables are present here, one for data obtained through Cycle 26 and one for data obtained through Cycle 27. Information regarding pixel history and updates to the bad pixel table can be found in WFC3 ISRs 2019 03 and 2019 04. Since launch, a litany of circular aberrant regions called blobs have appeared in IR images. These blobs are regions of lower sensitivity that appear due to bits of epoxy from the CSM motor shafts depositing onto the mirror. Tracking and flagging these blobs in the IR bad pixel table is therefore imperative so that they may be masked in any science images where they may appear. Information regarding blobs can be found in WFC3 ISR 2018 06. The Cycle 26 bad pixel table includes a blob that appeared on MJD 58464. The Cycle 27 bad pixel table includes two blobs that appeared on MJD 58804 and MJD 59047. The existing table for the blob that appeared in MJD 58464, with useafter of December 12 2018, uses Cycle 25 bad pixel data, though it appeared during Cycle 26. Likewise the existing tables for the blobs that appeared on MJD 58804 and MJD 59047, useafter of Nov 17 2019 and Jul 17 2020, use Cycle 25 bad pixel data though they appeared during Cycle 27. The three files are being updated to reflect the bad pixel history concurrent with the appearance of the blob, such that the Cycle 26, useafter Dec 12 2018, blob contains Cycle 26 bad pixel data, while the Cycle 27 blobs contain Cycle 27 bad pixel data.

Update to reference file for blue modes G130M/1055 and 1096, fitting over voltage change discontinuity, obtained using python analysis scripts cos_tds_analysis.py, make_tds_reference.py. Data values for the standard modes are unchanged, and are copied from the previous reference file. A new breakpoint was introduced at 2019.0 to match the standard modes. All slopes are updated to account for the flux calibration with the blue modes FLUXTAB and FLAT, and slopes were updated to model data up to October 2020. The G140L/1105B and 800B rows were removed as they are not supported modes.
2021-02-22 hst_0861.pmap archived Updated FLUXTAB being delivered. The following changes affect COS FUVB. Every change listed here corresponds to two rows, one for the PSA aperture and one for the BOA aperture. 1. An error was found in cenwaves 1055 and 1096 where the previously delivered fluxtab was orders of magnitude off for the bluest about 1 Angstrom of each segment. This error was corrected. 2. The fluxtabs for cenwaves 1055 and 1096 were updated using the new time dependent sensitivity, TDSTAB, being delivered at the same time but as a separate delivery. 3. The rows for G140L/1105 FUVB was removed. That mode is not an allowed mode. This change should be transparent to the user, since CalCos did not use that row because there are no data with that specifications. It was done for conciseness.

Further we also updated the pivot wavelengths in the aperture file. Lastly, we want the version numbers of the updated time dependent synphot files to continue to match the non time dependent synphot files so we update the version of those files for redelivery as well.

2020-12-02 hst_0846.pmap archived Intrinsic excess thermal energy trapped in the silicon lattice of the Wide Field Camera 3, WFC3, ultraviolet visible, UVIS, detector, known as dark current, is typically removed from science observations using UVIS dark calibration reference files. However, this dark current can be used as a means to characterize a pixels behavior and determine whether the pixel varies excessively over time compared to its expected noise. We use a novel data structure known as a pixel history image to efficiently evaluate each WFC3 UVIS pixel over time. We find that the vast majority of hot pixels, about 8 percent of the detector in 2018, are in fact quite stable and as such, can be calibrated. A small portion of pixels, less than 1 percent, are genuinely unstable and should not be used. To encode this distinction in the UVIS bad pixel reference files, we employ a data quality flag, 32, to mark the unstable pixels identified in this study. Hot pixels continue to be assigned the usual data quality flag, 16. With the additional data quality flag, WFC3 UVIS users will have enhanced control over which pixels to include, and which to exclude, in their analyses. This new bad pixel table was generated using the most recent complete anneal period, and therefore accurately captures the most current bad pixel map of the UVIS detector. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15.

However, since the USEAFTER dates for these new files are different from the old, after the new files are delivered, the old reference files, with a USEAFTER of Jan 15 2015, will need to be removed from CRDS.
2020-11-06 hst_0839.pmap archived A bug was found in the ACS reference file pipeline that was causing the noise in the ERR arrays of flashed superdarks to be underestimated. ACS started post-flashing their daily monitor darks on 2015-01-19, so all anneal superdarks and cte-corrected superdarks since that time have been affected by this. The bug in the pipeline has since been fixed, and the affected ACS WFC superdarks and cte-corrected superdarks have been regenerated to show the correct values in ERR arrays.

2020-10-15 hst_0836.pmap archived These new WFC3 delta flats correct for IR blobs, which are small regions with reduced sensitivity in calibrated images. The flats were derived by stacking inflight observations of sparse fields after each blob appearance date, thus illuminating the detector with a deep, combined image of the sky background. These flats are intended to be used in combination with new pixel flats derived by Mack et al. 2020, which improve the pixel to pixel sensitivity calibration with wavelength. During the flat fielding step, the WFC3 calibration software will correct each image by the product of the pixel flat and the delta flat reference files. The delta flats will be used in IR data taken in the F098M, F105W, F110W, F125W, F140W, and F160W filters for 49 unique blob appearance events, and correct for 148 strong and weak blobs appearing through 10 July 2018 with errors of less than 1 percent. More information can be found in Olszewski et al. 2020, WFC3 ISR in prep., WFC3/IR Blob Flats.
2020-10-15 hst_0835.pmap archived For the WFC and HRC IMPHTTAB files, new CALSPEC SEDs of the primary flux reference standard stars changed the ACS WFC and ACS HRC absolute flux calibration by about 1 to 2 percent. New results from 4 years of ACS WFC monitoring observations of those standard stars also contributed updates. These both require updates to the IMPHTTAB to generate correct PHOTFLAMs for files processed by CALACS. The SBC IMPHTTAB file is being delivered because new throughput tables were produced for the SBC. These changes were triggered by updates to CALSPEC SEDs. This new file updates the zero points to reflect these changes. Zeropoints changed by about 1 to 2 percent.
2020-10-15 hst_0834.pmap archived A new set of UVIS and IR inverse sensitivities incorporate improvements to the HST CALSPEC models, Bohlin et al. 2020, as well as an increase in the Vega reference flux. As a consequence, the standard white dwarf fluxes increase by about 2 percent for wavelengths in the range 0.15 to 0.4 micron and about 1.5 percent in the range 0.4 to 1.6 micron covered by both detectors. Also, the UVIS calibration also includes new corrections for temporal changes in the detector sensitivity derived from over 10 years of monitoring data, Calamida et al. 2020. This new method corrects the image header inverse sensitivity keyword, PHOTFLAM, to account for changes of about 0.1 to 0.2 percent per year according to the filter, improves the chip-sensitivity ratio, PHTRATIO, in FLT and FLC data by up to 1 percent, in agreement with early dithered star cluster and standard white dwarf observations, improves the encircled energy correction by about 1percent in the ultraviolet filters and by about 0.5 percent at wavelengths larger than 7,500 A, in close agreement with the 2009 EE values.
2020-10-15 hst_0833.pmap archived Initial WFC3 delta flat - DFLTFILE - rmap. See JIRA issues CRDS-379 and CCD-735 for more details.
2020-10-15 hst_0832.pmap archived The COS flat field rmap is being updated to have the new NUV flat, 4ae20499l_flat.fits, as the file to be used for NUV data taken since May, 2009. CRDS rules prevented the previous file from being directly replaced.
2020-10-14 hst_0831.pmap archived The COS FLATFILE being delivered is identical to x5v1944hl_flat.fits except that the first extension header keywords have been added back in after being dropped from the file in 2009. The main keyword that is needed is SNR_FF which is part of the calcos error calculations.
2020-10-12 hst_0830.pmap archived These new Pflats were computed by stacking deep exposures of sparse fields with sources masked over the WFC3 lifetime. They replace the prior set of reference files, which were based on the original ground flats, multiplied by a grey sky flat correction from inflight data through 2010. The new sky flats correct for wavelength-dependent residuals of plus or minus 0.5 percent at the center of the detector and 1-2 percent at the detector edges, with Poisson errors about 0.2 percent or better. For details, see Mack et al. 2020, WFC3 ISR in prep., WFC3/IR Filter-Dependent Sky Flats. An accompanying set of delta Dflats corrects for 148 known IR blobs in six filters as a function of date. These were computed by stacking the sky flat observations after the appearance of each blob and correct for losses as large as about 30 percent at the blob center with less than 1 percent errors. For details, see Olszewski et al. 2020, WFC3 ISR in prep., WFC3/IR Blob Flats.
2020-10-08 hst_0829.pmap archived These WFC3 UVIS superdarks, drk, and CTE corrected superdarks, dkc, will affect all UVIS data taken from September 3rd through September 29th 2020. Currently, the automated calibration pipeline and Calibration Reference Data System only have WFC3 UVIS drk and dkc reference files up to a USEAFTER date of August 31st 2020. The automated pipeline should now use these reference files to perform dark subtraction on any UVIS datasets obtained between the dates above because they represent the most accurate estimate of the dark current and hot pixels at the time of the science observation. These WFC3 UVIS drk and dkc files were generated using dark exposures from the HST Cycle 27 daily monitoring program 15716. More information regarding the method used to create UVIS dark calibration reference files can be found in WFC3 ISR 2016 08. Additionally, the header of each reference file has a detailed history section outlining the process and provides a list of datasets used to create each file.
2020-10-05 hst_0828.pmap archived The trends in the FUV sensitivity were not being adequately tracked by the current TDS model. Therefore revised parameters were derived for the slopes and incorporated into the new TDSTAB for the standard modes G130M 1222, 1291, 1300, 1309, 1318, 1327, G160M 1577, 1589, 1600, 1611, 1623, G140L 1105, 1230, 1280. Then, the TDS parameters were used to back out the sensitivities at the reference time, which were then used to update the FLUXTAB reference file for LP4 and to provide a new FLUXTAB file for LP3, with the latter having a USEAFTER date matching that of the TDSTAB reference file.
2020-10-05 hst_0827.pmap archived Intrinsic excess thermal energy trapped in the silicon lattice of the Wide Field Camera 3, WFC3, ultraviolet visible, UVIS, detector, known as dark current, is typically removed from science observations using UVIS dark calibration reference files. However, this dark current can be used as a means to characterize a pixels behavior and determine whether the pixel varies excessively over time compared to its expected noise. We use a novel data structure known as a pixel history image to efficiently evaluate each WFC3 UVIS pixel over time. We find that the vast majority of hot pixels, about 8 percent of the detector in 2018, are in fact quite stable and as such, can be calibrated. A small portion of pixels, less than 1 percent, are genuinely unstable and should not be used. To encode this distinction in the UVIS bad pixel reference files, we employ a data quality flag, 32, to mark the unstable pixels identified in this study. Hot pixels continue to be assigned the usual data quality flag, 16. With the additional data quality flag, WFC3 UVIS users will have enhanced control over which pixels to include, and which to exclude, in their analyses. This new bad pixel table was generated using the most recent complete anneal period, and therefore accurately captures the most current bad pixel map of the UVIS detector. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15.
2020-09-29 hst_0826.pmap archived Following the delivery of throughput tables for ACS WFC and ACS HRC modes, an error was noticed in some of the filter files where the header keyword TUNIT1 was missing. The keyword has since been defined with the correct value of ANGSTROMS and the updated files need to be delivered to CRDS. See JIRA tickets ACS-134 and RFD-648 for more info.
2020-09-28 hst_0825.pmap archived New CALSPEC SEDs of the primary flux reference standard stars changed the ACS WFC and ACS HRC absolute flux calibration by roughly 1-2 percent. New results from 4 years of ACS WFC monitoring observations of those standard stars also contributed updates.
2020-09-28 hst_0824.pmap archived The STIS team is delivering new throughputs for all STIS modes ahead of the ETC 29.1 release. For the MAMA detectors, these new throughputs only contain changes to the evaluation date - from mid-cycle 28 to mid-cycle 29. For the CCD, in addition to the evaluation date change, the underlying TDS was changed to the most recent CCD TDS delivered in October 2019.
2020-09-23 hst_0823.pmap archived The synphot files for the blue-mode cenwaves, G130Mc1055 and G130Mc1096, were updated based on updated FLUXTAB, TDSTAB, and DISPTAB reference files for these modes.
2020-09-22 hst_0822.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Sep 19, 2020, and should be used to calibrate ACS WFC observations taken between July 20, 2020 and Sep 19, 2020.
2020-09-18 hst_0821.pmap archived The throughput table has been updated, reducing throughput by roughly 2 percent. This is due to a small change in the absolute flux of the CALSPEC stars that are used as input for this program. This file replaces the current MAMA throughput table.

2020-09-17 hst_0819.pmap archived has been replaced by 49g17153l_disp.fits to improve accuracy to 3 pixels for 2 wavelengths.
2020-09-16 hst_0818.pmap archived We delivered two updated reference files DISPTAB and SPWCSTAB, in an effort to revise the wavelength calibration of the COS FUV blue modes G130M1055 and G130M1096, and achieve a relative accuracy of 3 pixels. The git-tag entry is disp_spwcs_2020Aug6 bm. In the new DISPTAB, the BOA values were copied from the PSA for all updated cenwaves, i.e. 1055 and 1096. The other standard cenwaves data were copied from the old DISPTAB, 0bn1606sl_disp.fits, because these modes were not updated in this effort. In the new SPWCSTAB, we updated the values of CRVAL1 and CRDELT1 for the revised cenwaves, while we copied all these values for the other standard cenwaves from the old SPWCSTAB, 2bj2256kl_spwcs.fits.
2020-09-11 hst_0817.pmap archived These WFC3 UVIS superdarks, drk, and CTE corrected superdarks, dkc, will affect all UVIS data taken from July 7th through August 31st 2020. Currently, the automated calibration pipeline and Calibration Reference Data System only have WFC3 UVIS drk and dkc reference files up to a USEAFTER date of July 5th 2020.

2020-09-03 hst_0816.pmap archived 49120309j_ccd.fits has an incorrect USEAFTER date. A file with the correct USEAFTER has already been delivered
2020-09-02 hst_0815.pmap archived After the anneal on July 20, 2020, the ACS/WFC amp D read noise, CCDGAIN = 2, increased significantly. After the anneal on August 20, 2020, the read noise stabilized at a mean of 5.65 electrons, compared to 5.05 electrons previously. This updated CCDTAB includes the new read noise for amp D. A previous delivery of this file included the wrong USEAFTER date, which has since been updated to the reflect the correct value of July 24, 2020. The HST context was not updated for the previous delivery, so we are now delivering the correct file in its place.

2020-08-13 hst_0811.pmap archived New weekly biases and darks were created for the new anneal month and need to be delivered for GO observations. These files are available for STIS CCD observations taken after 8 April 2020.
2020-08-07 hst_0810.pmap archived These new STIS FUVMAMA PHOTTAB reference files contain updated sensitivity curves for all postSM4 E140M observations. The E140M grating started showing evidence of blaze function shape changes in 2012, that over time resulted in relative flux calibration errors outside of specifications in the STIS IHB. These files include new derivations of the E140M throughput curves from observations of G191B2B and new derivations of the blaze function shift coefficients from monitoring observations of BD 28D4211. New E140M ripple tables were also derived and are being delivered concurrently. The new STIS FUVMAMA RIPTAB files contain updated, normalized sensitivity curves for postSM4 E140M observations. The E140M grating started showing evidence of blaze function shape changes in 2012, that over time resulted in relative flux calibration errors outside of specifications in the STIS IHB. The derivation of new sensitivity curves for the PHOTTABs required the creation of new, self-consistent ripple functions to be delivered concurrently.
2020-07-30 hst_0809.pmap archived The COS NUV TDSTAB was updated because the previous file, delivered in 2010, overestimated subsequent declines in sensitivity. This had the effect of overcorrecting recent spectra and giving flux errors outside the 5 percent tolerance. In the new file, slopes and intercepts were updated for all stripes of G185M, G225M, and G230L. Due to its sharply reduced sensitivity and lack of GO use since 2013, the parameters for G285M were not updated. Parameters were determined from fits to spectra obtained in the ongoing NUV Spectroscopic Sensitivity Monitor program. The August 2019 breakpoint present in previous NUV TDSTABs was removed.
2020-07-27 hst_0808.pmap archived These files were generated following the ACS WFC anneal on July 20, 2020, and should be used to calibrate ACS WFC observations taken between June 26, 2020 and July 20, 2020.
2020-07-22 hst_0807.pmap archived Throughout the lifetime of WFC3, a growing number of blobs small, circular regions with slightly decreased sensitivity have appeared in WFC3 IR images. These blobs appear due to particulates on the channel select mechanism CSM the movable mirror that is used to direct light into either the UVIS or IR channels of the instrument. These particulates are likely cracked epoxy originating from two pins joining the CSM motor shafts to the alignment bellows, therefore, it is critical that blob accumulation is monitored as a growing number of blobs may signify a loosening of these pins, and thus a defective CSM. Furthermore, the flagging of these blobs in the IR bad pixel table ensures that all of the blobs are masked in any science images where they may be present. More information can be found on WFC3 2018 06
2020-07-21 hst_0806.pmap archived A new FLATFILE used only for LP2 G130M cenwave 1055 and 1096 data has been delivered to TEST. The current rules select on only LP and optical element, so the rmap has been updated to include a cenwave selection for these two cenwaves.
2020-07-21 hst_0805.pmap archived New TDSTAB reference file for blue modes G130M/1055 and 1096, fitting over voltage change discontinuity, obtained using python analysis scripts cos_tds_analysis.py, make_tds_reference.py. Data values for the standard modes are unchanged, and are copied from 43n19046l_tds. A new breakpoint wasintroduced at 2015.5 to match the normal modes cenwaves. All slopes are updated to account for the new flux calibration with the new blue modes FLUXTAB and FLAT, and slopes were updated to model data up to March 2020. The file was tested by comparing all TDS observations since SM4 to a reference model. This reference file needs to be used with new_phot.fits and new_flat.fits files delivered on the same date.
2020-07-21 hst_0804.pmap archived The phot file is being delivered as part of the overall effort to better flux calibrate COS far ultraviolet cenwaves 1055 and 1096. These are the two bluest modes on HST at intermediate resolutions. The file is a modification to contain new sensitivity functions for these two modes, meaning the first eight rows have been modified. This file should be used along with the newly provided flat field. This new calibration has improved the flux accuracy of these modes from errors of about 20 percent to the requirement of less than 5 percent.
2020-07-21 hst_0803.pmap archived This flat field file is being delivered as part of the overall effort to better flux calibrate COS far ultraviolet cenwaves 1055 and 1096. These are the two bluest modes on HST at intermediate resolutions. Due to different detector response at such far blue wavelengths a new flat file apart from the one used for the standard cenwaves is needed. This file should be used along with the newly provided sensitivity function. This new calibration has improved the flux accuracy of these modes from errors of about 20 percent to the requirement of less than 5 percent.

We find that the vast majority of hot pixels about 8 percent of the detector in 2018 are in fact quite stable and as such can be calibrated. A small portion of pixels about 1 percent are genuinely unstable and should not be used. To encode this distinction in the UVIS bad pixel reference files we employ a data quality flag 32 to mark the unstable pixels identified in this study. Hot pixels continue to be assigned the usual data quality flag 16. With the additional data quality flag WFC3 UVIS users will have enhanced control over which pixels to include, and which to exclude in their analyses. This new bad pixel table was generated using the most recent complete anneal period, and therefore accurately captures the most current bad pixel map of the UVIS detector. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15.

2020-04-07 hst_0781.pmap archived The format of the TDSTAB has changed to include a new CENWAVE column in anticipation of a cenwave-dependent TDS correction in the FUV. Furthermore, the NUV TDSTAB had to include all of the cenwaves instead of treating the new cenwave column with a wildcard value as in previous versions. The CAL_VER keyword also needed to be updated from 3.3.8 to 3.3.9, due to CalCOS versioning.

2020-03-25 hst_0779.pmap archived These WFC3 UVIS superdarks, drk, and CTE corrected superdarks, dkc, will affect all UVIS data taken from February 19th through March 16th 2020. Currently, the automated calibration pipeline and Calibration Reference Data System only have WFC3 UVIS drk and dkc reference files up to a USEAFTER date of February 16th 2020. The automated pipeline should now use these reference files to perform dark subtraction on any UVIS datasets obtained between the dates above because they represent the most accurate estimate of the dark current and hot pixels at the time of the science observation. These WFC3 UVIS drk and dkc files were generated using dark exposures from the HST Cycle 27 daily monitoring programs 15714 and 15715. More information regarding the method used to create UVIS dark calibration reference files can be found in WFC3 ISR 2016 08. Additionally, the header of each reference file has a detailed history section outlining the process and provides a list of datasets used to create each file.

2020-03-20 hst_0777.pmap archived Intrinsic excess thermal energy trapped in the silicon lattice of the Wide Field Camera 3, WFC3, ultraviolet visible, UVIS, detector, known as dark current, is typically removed from science observations using UVIS dark calibration reference files. However, this dark current can be used as a means to characterize a pixels behavior and determine whether the pixel varies excessively over time compared to its expected noise. We use a novel data structure known as a pixel history image to efficiently evaluate each WFC3 UVIS pixel over time. We find that the vast majority of hot pixels, 8 percent of the detector in 2018 are in fact quite stable and as such, can be calibrated. A small portion of pixels, less than 1 percent, are genuinely unstable and should not be used. To encode this distinction in the UVIS bad pixel reference files, we employ a data quality flag, 32, to mark the unstable pixels identified in this study.

2020-03-18 hst_0774.pmap archived The ACS HRC CCDTAB files j4d1435kj_ccd.fits and m711125gj_ccd.fits need to be removed from CRDS because they are no longer used by any data. A search w for unique CCDTAB file names for HRC data was performed, and found that the two files are unused. The need to remove these files was initiated when new ACS HRC CCDTAB reference files were delivered to HST TEST and it was discovered that j4d1435kj_ccd.fits was missing the header END card. This discovery led the ACS team to request the removal of both j4d1435kj_ccd.fits and m711125gj_ccd.fits because neither files are used by any data.

2019-07-01 hst_0714.pmap archived Updated NUVMAMA PHOTTAB reference file. This file includes derivations of the echelle blaze function shift coefficients for the E230M grating. The temporal coefficients of the blaze shift have been updated using post SM4 E230M 1978 monitoring observations of BD 28D4211. Without the updates the relative photometric accuracy of some recent observations are approaching being outside of specifications in the STIS IHB.
2019-06-20 hst_0713.pmap archived TDCTAB is used to derive a factor that gets multiplied to the NUVMAMA dark reference file before the dark subtraction. We found that the older TDCTAB is not scaling the dark correctly for data taken after Jan 1, 2014, so we added 2 new rows to the TDCTAB to correctly scale the dark.
2019-06-18 hst_0712.pmap archived Removes the ACS SBC P-FLAT from the PFLTFILE rmap. This file was delivered to CRDS for storage purposes in case the need arises to retrieve it in the future. Only LP-flats should be used to calibrate ACS data.
2019-06-17 hst_0711.pmap archived Updated LP-flats for the ACS SBC have been created. The SBC P-flat was updated following ACS ISR 2016-02, which found that coherent pixel-to-pixel variations remained stable in the period 2002-2007, and then after a change have remained stable from 2007 to present. The creation of a new 2007 SBC P-flat necessitated the creation of new LP-flats with this USEAFTER date. In addition, the method for creating SBC L-flats was updated to use a new 2D fitting algorithm rather than a checkerboard. The L-flats were created using many more observations than were available for the previous delivery. This delivery includes a copy of the SBC P-flat for future reference by the ACS team. The P-flat will be removed from the rmap in the next context update as it should not be used to calibrate data and only LP-flats should be used for ACS data calibration.

2019-05-07 hst_0698.pmap archived These files were replaced with more recent data.
2019-05-07 hst_0697.pmap archived These new WFC3 IR bad pixel tables and superdarks, described in detail in WFC3 ISR 2019 03 and 04, incorporate a time dependence in order to better calibrate and flag those detector pixels that have changed their behaviors since launch, e.g. a pixel that has become hot or unstable since launch, or regained its stability since launch. They were also created using many more years worth of calibration data since the previous releases which significantly reduces the errors associated with their creation, and allows for more accurate dark calibrations and bad pixel flags. The IR Blob flags are also all shifted to correctly match those center positions recorded in WFC3 ISR 2018 06. The new MDRIZTAB parameter file, which is designed to work with these new WFC3 IR bad pixel tables and superdarks, contains significant changes to the default drizzling parameters for WFC3 IR and is described in detail in WFC3 ISR 2019 05. These changes include treating stable hot pixels, which are now well cali brated in the new superdarks, as good, optimized cosmic ray rejection parameters to prevent improper flagging of point soures, improved sky subtraction, and better handling of single input frames. Delivered by Ben Sunnquist for WFC3.
