Start Date Context Status Description
2025-10-23 roman_0041.pmap latest 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.
2025-10-22 roman_0040.pmap archived The updated linearity and inverse linearity reference files had an incorrect useafter date attribute in their meta data. Removing these files and will resubmit files with the correct useafter date.
2025-10-21 roman_0039.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
2025-10-09 roman_0038.pmap archived Delivering new wfi flat, readnoise, and epsf rmaps to facilitate tvac decommissioning. The new epsf rmap has been modified to allow for L3 processing to choose for each filter the epsf reference file for detector WFI02. In testing an additional NA value pointing to the same reference file for filter was used by default in romancal when looking for a reference file, see CRDS-1031 for more details. The new readnoise rmap adds WFI_SPECTRAL and WFI_WFSC for each entry, see CCD-1663 for more details. The new flat rmap adds N/A entries for each optical element, see CCD-1664 for more details.
