Context History (more history, all contexts)

Start Date Context Status Description
2024-04-18 hst_1153.pmap operational These WFC3 UVIS superdarks will affect all UVIS data taken from December 7, 2023, to March 28, 2024. Currently, the automated calibration pipeline and CRDS have only WFC3 UVIS drk and dkc reference files with USEAFTER dates of up to December 7, 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 31 CAL programs 17345, 17347, and 17348. 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. These three new bad pixel tables with USEAFTERs of January 08, 2024, February 07, 2024, and March 09, 2024 were generated using data taken from January 08, 2024, through April 01, 2024. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of December 07, 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 31 daily monitoring programs 17345, 17347, and 17348. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
2024-04-08 hst_1151.pmap archived Delivery of corrected STIS CCD bias and dark reference files for CCD data taken between February 23 to March 8 and July 27 to August 25, 2023. The files were generated from data taken in the same time frame under STIS calibration programs 16949, 16950, and 16946. The sets of input files were corrected to better match the reference file USEAFTER dates. Delivery of new STIS CCD bias and dark reference files for CCD data taken between January 24 and March 19, 2024. The files were generated from data taken in the same time frame under STIS calibration programs 17377, 17374, and 17375.
2024-04-02 hst_1149.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on March 25, 2024, and should be used to calibrate ACS WFC observations taken between February 26, 2024 and March 25, 2024.
2024-03-29 hst_1148.pmap archived New STIS NUVMAMA and CCD throughputs are being delivered for ETC version 32.2. Throughputs are updated due to changes in the NUVMAMA and CCD TDSTABs. There are no changes to the FUVMAMA throughputs, and these files are evaluated to match the MJD evaluation date of ETC version 32.2.
