Context History (more history, all contexts, build contexts)

Start Date Context Status Description
2026-01-09 roman_0044.pmap latest Delivering a new WFI dark rmap that removes MA_TABLE_NUMBER as a selection criteria because this keyword is not needed for selection of the dark reference files.
2025-12-09 roman_0043.pmap archived The new ePSF files are updated to include jitter metadata for testing SOC Build 20.
2025-11-18 roman_0042.pmap archived The Roman WFI readnoise rmap was missing the WFI_LOLO exposure type, which was preventing DMS from being able to process Roman MRT data taken in the LOLO mode. This new WFI readnoise rmap is being delivered with WFI_LOLO added to the exposure type list for all entries.
2025-10-23 roman_0041.pmap archived Updated linearity and inverse linearity reference files have been recentered to accommodate stcal implementation of the linearity correction. Additionally, new dg arrays include the NO LIN COR for pixels that did not round trip but file conversions less than 200 DN. This is the follow up delivery for updating these files.
