2020-10-15 hst_0836.pmap operational For the delivery of new ACS IMPHTTABs, WFC3 IMPHTTABs, and the initial delivery of WFC3 delta-flat reference files.
2020-10-15 hst_0832.pmap archived The reason is the deliveries of a new COS NUV flat and updated COS flatfile rmap.
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.
2020-10-09 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.
2020-10-06 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.
2020-09-30 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.
2020-09-29 hst_0825.pmap archived The reason is the STIS and ACS synphot deliveries yesterday.
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.
2020-09-23 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.
2020-09-21 hst_0821.pmap archived The reason is the delivery of a new ACS SBC throughput table and TMC file.
2020-09-17 hst_0819.pmap archived has been replaced by 49g17153l_disp.fits to improve accuracy to 3 pixels for 2 wavelengths.
2020-09-17 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.
2020-09-14 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.

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.
2020-09-03 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 The reason is a new ACS CCDTAB file was delivered.
2020-08-26 hst_0813.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on August 20, 2020, and should be used to calibrate ACS WFC observations taken between July 20, 2020 and August 20, 2020.

2020-08-17 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.
2020-07-28 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.
2020-07-23 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
2020-07-21 hst_0806.pmap archived The reason is 3 files, a COS TDSTAB, FLATFILE, and FLUXTAB that were originally delivered to TEST have been delivered to OPS. There has also been an RMAP update for the FLATFILE.
2020-07-15 hst_0802.pmap archived These WFC3 UVIS superdarks, drk, and CTE corrected superdarks, dkc, will affect all UVIS data taken from June 12th through July 5th 2020.

2020-06-05 hst_0797.pmap archived Raw darks were taken from proposal 15769 and processed using CALACS Version 10.2.2. They were then 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 using the. The intermediate data product was smoothed with a local median filter to produce the final post-flash file.
2020-06-04 hst_0796.pmap archived These files were generated following the ACS WFC anneal on May 29, 2020, and should be used to calibrate ACS WFC observations taken between Apr 28, 2020 and May 29, 2020.

2020-05-18 hst_0793.pmap archived MJDs for ACS and other instruments were updated in the test_pysynphot_tmc.py script by Matt McMaster in May 2020 to relevant dates. Previously, many had been outside the operational timeframes of the instruments and were causing stsynphot to issue warnings during synphot submission with the new automated process. This delivery incorporates those changes into the table of the OBSMODES file.
2020-05-13 hst_0792.pmap archived SBC UV contamination monitor data was taken on 2020-04-14. A new IMPHTTAB needs to be delivered for inclusion into CRDS.

2020-04-23 hst_0787.pmap archived These new ACS WFC and HRC CCDTAB reference files have been updated to include three additional columns. Two columns to represent the commanding overheads, post-flashed vs unflashed, with values that are applied as an additive correction to the DARKTIME keyword and one column to represent updated A-to-D saturation levels for accurate flagging in CALACS. Files were previously delivered to HST TEST for development of new CALACS build to encompass these changes.

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.

Currently, the automated calibration pipeline and Calibration Reference Data System is missing this file due to a mistake in the original delivery. The automated pipeline should now use this reference files to perform dark subtraction on any UVIS datasets obtained between the dates listed above because it represent the most accurate estimate of the dark current and hot pixels at the time of the science observation. This WFC3 UVIS drk files was generated using dark exposures from the HST Cycle 27 daily monitoring program 15714. 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.
2020-01-27 hst_0763.pmap archived The TDSTAB file for the new cenwave modes G160M/1533/A, B and G140L/800/A that were introduced at the time of commissioning of these modes were populated with values for the SLOPE and INTERCEPT that did not apply any correction to the data. The time-dependent sensitivity of these modes was included in the Cycle 26 FUV TDS monitoring program, and the data obtained have allowed us to characterize the TDS for these modes and update the values so the appropriate correction is applied.

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.

2019-10-18 hst_0745.pmap archived Some ACS SBC THCOMPNAME values were incorrectly specified in the last delivery of the Pysynphot TMG graph file. This new version will allow Pysynphot to generate the proper exceptions, which will be caught by the ETC code.
2019-10-17 hst_0744.pmap archived New STIS time dependent sensitivity, TDS, trends derived from on orbit observations taken between April 1997 and July 2019. Recent observations taken for TDS monitoring have begun to diverge from the extrapolated trends in the existing references files, particularly in the NUV. These files are for correcting the TDS in data taken post SM4, after May 1, 2009. However, in these new reference files the post SM4 TDS fits are now explicitly anchored to the pre SM4 TDS fits.

2019-09-30 hst_0740.pmap archived Currently CRDS does not contain WFC3/UVIS binned bias reference files for 2018. These files will be used to perform bias subtraction on any 2x2 and 3x3 binned WFC3/UVIS data with a USEAFTER of 2018-01-01. Furthermore, CRDS only has a 2x2 binned bias for aperture == UVIS1 with a USEAFTER of 1990 and 2008 so we are adding 2x2 binned biases for each year between 2009 - 2018 with aperture UVIS1

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.

2019-07-26 hst_0721.pmap archived This removes ACS shutter shading correction SHADFILE and analog-to-digital conversion ATODTAB reference files. 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.
2019-06-13 hst_0709.pmap archived Using new deuterium and Cycle 26 dark data, we updated the low response, very low response, background feature, and low pulse height amplitude feature regions flagged in the bad pixel table for COS FUV modes. This included updating the sizes of regions flagged previously, as well as searching and adding new regions to the file. We also added the enhanced dark count edge regions on FUVA to the file as a new DQ value, 16384.
2019-06-06 hst_0708.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 16 March 2019.
2019-06-05 hst_0707.pmap archived These files are meant to calibration STIS CCD data taken after 16 March 2019, but they were not renamed in the normal format. These should be deleted and marked as bad so that they are not used.

2019-05-22 hst_0704.pmap archived New TMC file incorporating changes to ACS throughput tables. Quick fix tables correct the SBC detector throughput to remove 30 percent zeropoint error. 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. Previous rmap only matched observations taken in the aperture named WFC instead of all apertures. Pre SM4 ACS WFC data use either the full-frame bias or a cutout of the full-frame bias to calibrate 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.

2018-12-28 hst_0678.pmap archived WFC3 had an error in the USEAFTER date for file 2ck18541i_bpx.fits, this incorrectly removed u5d2012li_bpx.fits from the rmap. USEAFTER of the new file was fixed in the rmap and the 2009 bpix file was put back in the rmap. The USEAFTER in the header of the 2ck18541i_bpx.fits file was not modified.
2018-12-20 hst_0677.pmap archived New WFC3 UVIS bad pixel tables include flags value 8 for pixel instability, as described by WFC3 ISR 2018.15, and the new bad pixel table changes how the WFC3 team is flagging pixels.
2018-12-14 hst_0675.pmap archived These files are used in the dark current subtraction for WFC3 UVIS products from the December 2017 anneal until the last delivery just before the June 2018 anneal. They are a redelivery of an updated version of all those darks previously delivered during that time period. The previous versions were using the November 2017 masterdark to replace hot pixel values which, over time, lead to a false offset. This redelivery will correct all the darks from December 2017 until June 2018 to ensure the correct masterdark is used for the different anneals to ensure the dark current is correctly calculated. Delivered by Catherine Martlin for WFC3.
2018-12-11 hst_0674.pmap archived Standard delivery of ACS WFC superbias, superdark, and sink pixel reference files following the anneal on December 6, 2018.

2014-02-10 hst_0048.pmap archived These post-flashed dark current files continue the temporal monitoring of the UVIS channel dark current and have useafter dates of January 29th and 30th, 2014. 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.
