Context History (more history, all contexts)

Start Date Context Status Description
2024-04-02 roman_0057.pmap operational The Roman WFI flat rmap is being updated such that each flat reference file applies to all imaging filters, rather than just F158.
2024-02-07 roman_0056.pmap archived New dark reference file for WFI spectral GRISM mode for romancal testing of 16 resultant data
2024-02-06 roman_0055.pmap archived This is a new 16 resultant dark reference file to support Build 13 using a new read pattern for testing purposes. Updating read noise reference file for development of romancal and updating flagged inverse linearity reference files from DCL data.
2024-01-31 roman_0053.pmap archived Updating the read noise reference file to a higher value to support Build 13 testing or romancal.
