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. 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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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.

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. |

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. |

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. |

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. |

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. |

Due to this, the COS/NUV and COS/FUV sensitivity curves, found within the FLUXTAB reference files 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. |

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. |

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. |

These WFC3 UVIS superdarks and CTE-corrected superdarks will affect all UVIS data taken from December 21, 2021, to January 15, 2021. Currently, the automated calibration pipeline and CRDS have only WFC3 UVIS drk and dkc reference files with USEAFTER dates of up to December 18, 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. 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. |

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 October 6th, 2021 through October 23rd, 2021. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of September 9th, 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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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. |

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 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. |

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.

These WFC3 UVIS superdarks, drk, and CTE corrected superdarks, dkc, will affect all UVIS data taken from October 31st through November 24th 2019. 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 26th 2019. 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 26 and 27 daily monitoring programs 15571 and 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. |

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. |

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. |

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. |

The darks have had their DQ arrays updated to include the pixel stability flag, and the cte darks were all processed using the updated cte correction algorithm in CALACS v9.2.0. The darks were created from on orbit data taken between Mar 02 2012 and Dec 31 2012 by the ACS Reference Pipeline, the cte darks were created using reprocessdkc.py, which is a wrapper around the CTE correction scripts used by the ACS Reference Pipeline. This delivery contains ACS WFC full frame darks and cte darks with useafter dates between Mar 02 2012 04h 40m 12s and Dec 31 2012 00h 07m 31s and are suitable for data falling within that range.

The PCTERNOI keyword is used as an initial threshold criteria to determine the amplitude of the pixels signal above the readnoise of the detector. The current value of PCTERNOI is listed as 3.25, which is the readnoise of the WFC3 UVIS CCDs. The value has been changed to reflect the ACS WFC CCDs, which have an average readnoise of 4.3.

STIS reference file delivery. Previous IDCTAB for STIS FUVMAMA was a dummy file which included only the global linear distortions in X and Y.
We have recently derived a new geometric distortion solution for the STIS FUVMAMA detector, and this new reference
file implements the full fourth order polynomial coefficients to convert the raw X and Y positions to the rectified
X and Y positions. This new IDCTAB will be applied to ALL existing STIS FUVMAMA imaging data in the archive as well
as those obtained in future observations. A STIS ISR will be published describing the details of this new IDCTAB. |

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. |
