Start Date Context Status Description
2024-03-20 hst_1146.pmap operational 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. They were created with data from postflash calibration proposals 16982 and 17351. They include reference files for both shutters, A and B, and for both low and medium current. Two main tests were done, first a check of the changes from the previously submitted 2022 postflash files and second that the calwf3 pipeline is able to use them for proper application on UVIS data. All results were as expected.
2024-03-08 hst_1144.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on February 26, 2024, and should be used to calibrate ACS WFC observations taken between January 30, 2024 and February 26, 2024.
2024-03-08 hst_1143.pmap archived New synphot TMC and TMG files were delivered to update the ROMAN WFI element name from W146 to F146. New ROMAN WFI throughput reference files were also delivered to match the ones used by Webbpsf and Pandeia.
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.
2024-02-15 hst_1139.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on January 30, 2024, and should be used to calibrate ACS WFC observations taken between January 5, 2024 and January 30, 2024.
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.
2024-01-25 hst_1136.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from July 9, 2023, to December 7, 2023. Currently, the automated calibration pipeline and CRDS have only WFC3 UVIS drk and dkc reference files with USEAFTER dates of up to July 5, 2023. 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 30 and 31 daily monitor programs 16967, 17004, 17005, 17345, and 17347. 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.
2024-01-09 hst_1135.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on January 05, 2024, and should be used to calibrate ACS WFC observations taken between December 08, 2023 and January 05, 2024.
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.
2023-12-21 hst_1131.pmap archived All UVIS data taken from December 21, 2021, to August 29, 2022 and September 1, 2022, to November 22, 2022. These WFC3 UVIS superdarks will affect all UVIS data taken from December 21, 2021, to August 29, 2022 and September 1, 2022, to November 22, 2022. These drk and dkc reference files were generated using dark exposures from HST programs 16564, 16566, 16567, 16568, 16967, and 17003. These files will replace existing references. The automated pipeline should 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.
2023-12-20 hst_1129.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from January 23, 2021, to December 18, 2021. These drk and dkc reference files were generated using dark exposures from HST programs 16394, 16395, 16396, 16414, 16564, and 16566. 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.
2023-12-20 hst_1128.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from April 16, 2020, to January 20, 2021. These drk and dkc reference files were generated using dark exposures from HST programs 15712, 15715, 15716, 16394, and 16414. 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.
2023-12-14 hst_1127.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on December 08, 2023, and should be used to calibrate ACS WFC observations taken between November 07, 2023 and December 08, 2023. Due to the erratic behavior of Gyro 3, HST entered safe mode on November 19, 2023. This resulted in references for the November 07, 2023, anneal period to have less than the average number of calibration exposures, affecting some reference file statistics in an expected manner. New ACS WFC bias, dark, CTE-dark, and sink files are being delivered for the October 11, 2023, anneal period. The calibration frames from 2023-11-06 were mistakenly left out of the previous reference file creation. These files were remade and now include the missing 2023-11-06 calibration frames.
2023-12-11 hst_1125.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from August 5, 2019, to April 14, 2020. These drk and dkc reference files were generated using dark exposures from HST programs 15567, 15571, 15712, 15714, and 15715. 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. Two reference files were also deleted from the rmaps that were not properly replaced in the previous delivery.
2023-12-01 hst_1123.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between October 19 2023 and November 16 2023. The files were generated from data taken in the same time frame under STIS calibration programs 16950, 17377, 16948, and 17374.
2023-11-17 hst_1122.pmap archived Updating the single entry in the COS BADTTAB rmap to use NA for DETECTOR, so that this reference file will apply to all COS data - NUV and FUV. A new BADTTAB file will be delivered after this to replace the existing entry with an updated version.
2023-11-17 hst_1121.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from December 26, 2017, to August 2, 2019. These drk and dkc reference files were generated using dark exposures from HST programs 14978, 14980, 14981, 14982, 15567, 15569, 15570, and 15571. 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.
2023-11-14 hst_1119.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on November 7, 2023, and should be used to calibrate ACS WFC observations taken between October 11, 2023 and November 7, 2023.
2023-11-14 hst_1118.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from June 15, 2016, to December 23, 2017. These drk and dkc reference files were generated using dark exposures from HST programs 14366, 14369, 14370, 14529, 14531, 14532, 14533, 14978, and 14980.

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.
2023-11-10 hst_1116.pmap archived Updated ACS/SBC TDS files are being delivered that adjust the system throughput to reflect the changing sensitivity of the detector. These files are being delivered with new sensitivity measurements taken 2023 Mar 14, and are extrapolated to 2025-04-01. The default THROUGHPUT column matches that of the extrapolation date.
2023-11-10 hst_1115.pmap archived Updated COS synphot throughput files for ETC 32.1. These include throughput changes due to updating the FUV FLUXTAB and TDSTAB. These are evaluated at MJD=60766.
2023-11-09 hst_1114.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from October 5, 2015, to June 12, 2016.

Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of June 9, 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, 17004, and 17005. These four bad pixel tables were generated 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.
2023-11-06 hst_1111.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from December 4, 2014, to October 2, 2015. These drk and dkc reference files were generated using dark exposures from HST programs 14000, 14002, 14003, and 14004. These files will replace existing references. The automated pipeline should 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. This is the first official delivery of the WFC3 UVIS saturation map, sat, files, which will affect all full-frame and subarray UVIS data. The 1x1 saturation reference file will be applied to all 1x1 un-binned and subarray data. The 2x2 and 3x3 saturation file will be applied to all 2x2 and 3x3 binned data, respectively. The automated pipeline should now use these reference files to perform full-well saturation flagging on all WFC3/UVIS datasets to prepare them for spatially-variable full-well flagging. More information regarding the creation of the saturation map reference files can be found in an upcoming WFC3 Instrument Science Report by I. Rivera, M. Marinelli, J. Mack, 2023.
2023-10-30 hst_1108.pmap archived Updated ACS WFC synphot throughput tables are being delivered with a new extrapolation date for ETC 32.1. 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.
2023-10-27 hst_1107.pmap archived Initial delivery of WFC3 SATUFILE rmap for CRDS OPS.
2023-10-27 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.
2023-10-26 hst_1105.pmap archived These WFC3 UVIS superdarks will affect all UVIS data taken from November 8, 2012, to March 25, 2014. These drk and dkc reference files were generated using dark exposures from HST programs 13071, 13073, 13074, 13075, 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.
2023-09-19 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.
2023-08-31 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.
2023-08-18 hst_1098.pmap archived Delivery of new STIS CCD bias and dark reference files for CCD data taken between June 29 2023 and July 27 2023. The files were generated from data taken in the same time frame under STIS calibration programs 16950, 16947, and 16948.
2023-08-17 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.
2023-08-16 hst_1096.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. The darkfile and drkcfile rmaps were also updated to accommodate these new reference files.
2023-08-15 hst_1092.pmap archived Eight new bad pixel tables were generated using data taken from November 26, 2022 through July 08, 2023. 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. These eight bad pixel tables, and all future bad pixel tables, are generated using darks calibrated with the yearly postflash file. Seeing WFC3 ISR 2023.01 for info 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.
2023-08-04 hst_1089.pmap archived FLUXTAB and TDSTAB reference files were mistakenly delivered with a version of CalCOS that was a few versions above what is being used for the HST ops pipeline, resulting in some CalCOS failures. It was decided to rollback from hst_1090.pmap to hst_1089.pmap to fix this problem, until HSTDP-2023.2.0 is installed with CalCOS 3.4.7.
2023-08-03 hst_1090.pmap archived Update to 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.
2023-07-26 hst_1089.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on July 19, 2023, and should be used to calibrate ACS WFC observations taken between June 19, 2023 and July 19, 2023. Processing of recent ACS 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 ACS 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 ACS SBC IMPHTTAB was also generated and delivered to fix the issue with PHOTCORR being skipped.
2023-07-24 hst_1086.pmap archived An updated STIS NUV TDSTAB reference file is being delivered to reflect the latest TDS trends. Most changes affect wavelengths greater than 2400 A. Flux calibration improvements at the reddest wavelengths are on order of 1 - 1.5 percent. The STIS team is also delivering PHOTTAB, SPCTRTAB, RIPTAB, and IMPHTTAB reference files corresponding to the third flux recalibration release. These include updated flux files using CALSPECv11 models and new traces for secondary echelle modes. See the contemporaneous STAN article for more details.
2023-07-19 hst_1084.pmap archived hst_1084.pmap- These WFC3 UVIS superdarks will affect all CTE-corrected UVIS data taken from November 22, 2022, to July 5, 2023. Currently, the automated calibration pipeline and CRDS have only WFC3 UVIS drk and dkc reference files with USEAFTER dates of up to November 22, 2022. 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 30 programs 16967, 17003, and 17004. 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. hst_1083.pmap- These WFC3 UVIS superdarks will affect all UVIS data taken from November 22, 2022, to July 5, 2023.

2023-04-19 hst_1074.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. These are a delivery of new WFC3 UVIS postflash reference files for data taken after January 1st 2022. 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.

2023-02-23 hst_1067.pmap archived New ACS WFC CCDTABs were 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. 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.
2023-02-16 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_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_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.
2022-12-08 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.

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.

2022-09-23 hst_1041.pmap archived New WFC3 UVIS dark and cte-correct dark files were delivered. The files were generated using dark exposures from the HST Cycle 29 daily monitor programs, 16564 and 16568, and are to be used for the calibration of WFC3 UVIS data taken after August 6, 2022. A new COS FUV bad pixel table was delivered. In preparation for the LP6 era, the COS FUV BPIXTAB reference file needed to be updated in order to search for new low, DQ=1024, and very low, DQ=16, response regions in the LP6 area of the detector. In addition, regions in the previous BPIXTAB that were found to be invalid were removed or resized. This new file has added 24 new low response regions, and 13 new very low response regions for FUV A, and 10 new low response regions, and 7 new very low response regions for FUV B. Six regions were removed, and one region was re-sized.

2022-09-16 hst_1038.pmap archived A new COS NUV XTRACTAB was delivered because the background regions were too close to the PSA extraction regions. The updated XTRACTAB moves the background extraction regions closer to the edges of the detector which prevents over-subtraction from the PSA spectra and gives consistent flux values between the NUV and FUV arms. A new COS FUV SPOTTAB was also delivered because 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 new SPOTTAB file.
2022-09-14 hst_1036.pmap archived The COS team has delivered the first operational reference files for use at LP6, replacing the previous temporary LP6 reference files. The files delivered include a LAMPTAB, DISPTAB, XTRACTAB, TWOZXTAB, PROFTAB, TRACETAB, FLATFILE, and FLUXTAB. A second delivery included in this context update fixes a small selection issue with the COS flatfile rmap.

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.

2022-03-04 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.

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.

2021-10-18 hst_0961.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. This new bad pixel table was generated using data taken from September 9th, 2021 through October 5th, 2021. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of August 11th, 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.

2021-10-11 hst_0958.pmap archived These WFC3 UVIS superdarks and CTE-corrected superdarks will affect all UVIS data taken from September 8, 2021, to October 2, 2021. Currently, the automated calibration pipeline and CRDS only have WFC3 UVIS drk and dkc reference files up to a USEAFTER date of September 5, 2021. The automated pipeline should now use these reference files to perform dark subtractions on any UVIS datasets obtained between the dates above, as they represent the most accurate picture of the dark current and hot pixels for this range. These WFC3 UVIS drk and dkc files were generated using dark exposures from HST Cycle 28 daily monitoring programs 16396 and 16414. 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.
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.

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.

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 The reason is, new ACS WFC subarray and full-frame bias reference files were delivered.
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.

2021-04-21 hst_0875.pmap archived On April 20 2021 the new pixel based CTE correction was delivered to the calwf3 pipeline. This new pixel CTE correction table is that necessary table that enables the new CTE correction through calwf3. Every UVIS image in the archive should now have this file assigned as the PCTETAB so that the new CTE correction in calwf3 runs properly. This file is replacing the current CRDS PCTETAB zcv2057micte.fits. These new CTE corrected darks dkc are necessary for running the new CTE correction through calwf3. This first set is meant to allow any recent WFC3 UVIS data to be calibrated while the remainder of the dkc files are replaced over the next week. Lastly, we are also delivering the updated non-CTE corrected darks. These drk files will be using the current anneal masterdark instead of the previous anneal allowing for more time specific measurements. Delivering this anneal now allows continued processing while undergoing the delivery of all previous anneals over the next week.

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.

2021-01-11 hst_0852.pmap archived The temporal changes and updates delivered in the previous versions of the synphot files in 2020 are all still correct - this redelivery is to allow synphot packages such as pysynphot to properly interpolate values of the throughput between the beginning date MJD 55008 and the current first column in the tables. 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.

2020-12-11 hst_0849.pmap archived These WFC3 UVIS superdarks, drk, and CTE corrected superdarks, dkc, will affect all UVIS data taken from October 28th through November 25th 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 October 28th 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 and 28 daily monitoring programs 15716 and 16394. 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.

2020-12-02 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.

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.

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.

2020-07-23 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

2020-04-07 hst_0782.pmap archived Delivery of two new COS TDSTAB reference files. Additionally, an update to the COS TDSTAB rmap removed CENWAVE as a selector for these reference file types, and removed previous versions of the files.
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.
2020-03-25 hst_0778.pmap archived These files have COMPNAMEs which are either incorrect or no longer used. The filenames have been removed from the TMC, and are being removed from the rmap in order to ensure consistency. See JIRA issues REDCAT 88-92 for more information.
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. 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.
2020-03-19 hst_0776.pmap archived The reason is that new STIS Bias and Dark files were delivered and then some bias and dark files were removed creating an updated rmap for STIS Biases and Darks.
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.

2020-01-10 hst_0755.pmap archived There were approximately 200 extraneous COMPNAME values in the TMC which were not in the TMG. Since these names were missing from the TMG and were therefore never used. These COMPNAMEs were removed from the TMC, both as a prerequisite for further updates to CRDS in handling HST ETC files and the release of an HST ETC checking tool to the instrument teams. The TMG was updated to include the COMPNAME entries eso559 and nic3_205m, as well as their appropriate INNODE and OUTNODE values.

2019-08-12 hst_0725.pmap archived At the conclusion of each year there is an opportunity to create a new superbias, which involves combining together all of the bias frames from January through December. The WFC3 data reduction pipeline, calwf3, uses the superbias reference file to carry out the bias subtraction for all UVIS data. Once the new superbias is delivered it will be used for bias subtraction by every WFC3 image taken after 2018-01-01.
2019-08-12 hst_0724.pmap archived The WFC3 team has replaced dark files with new ones that have different USEAFTER dates. The new files are used in the dark current subtraction for WFC3 UVIS products for from August 2009 through October 2010. They were reprocessed to remove darks affected by scattered light and are scientifically more accurate for users. This update deletes files from the active context that did not have matching USEAFTER dates but that were effectively replaced.
2019-08-09 hst_0723.pmap archived These files are used in the dark current subtraction for WFC3 UVIS products for from August 2009 through October 2010. They were reprocessed to remove darks affected by scattered light and are scientifically more accurate for users.

These corrections are always set to OMIT in the pipeline and users never need to perform these corrections for ACS data. These files are based on ground/dummy data, and were mainly used to test the ACS calibration pipeline prior to launch.
2019-07-24 hst_0720.pmap archived Not available.
2019-07-19 hst_0718.pmap archived Removes SBC dark files from active context. SBC dark files are not used by the automatic pipeline, and users should see ACS ISR 2017-04 or contact the ACS Help Desk for questions about when and how to remove SBC dark current if necessary.
2019-07-16 hst_0717.pmap archived When using the MDRZTAB reference file for a single image, the AstroDrizzle TEAL GUI will crash because driz_sep_kernel value was INDEF, which was an unacceptable input value. This update changes driz_sep_kernel for N=1 images from INDEF to minmed, which prevents TEAL from crashing.
2019-07-15 hst_0716.pmap archived These files were generated following the ACS WFC anneal on June 26, 2019, and should be used to calibrate ACS WFC observations taken between May 31, 2019 and June 26, 2019.

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.
2019-06-18 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.
2019-06-17 hst_0710.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 08 May 2019.

This is a temporary set meant for Cycle 27 phase II preparations. The filter throughput tables contain a correction for the time dependent sensitivity, assuming and observation date of April 1, 2020 midcycle. The F115LP and F125LP filters still contain a 5 percent systematic offset. A refined set of tables will be delivered once the analysis is complete and Instrument Science Reports published.
2019-05-17 hst_0702.pmap archived Corrects biasfile aperture mapping for ACS WFC data taken before SM4.

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.

STIS darks & biases: New weekly biases and darks were created for the new anneal month to used with GO observations. COS hvtab: DQ flags have been slightly redefined and regions have been added, removed, or modified based on current data and detector understanding. In particular, data from COS FUV lifetime planning has enabled flagging of bad regions over a larger area of the detector than in previous implementation, and additional dark data has allowed a better qualification of what should or should not be flagged.
