Pipeline testing indicated that the MIRI MRS cube wavelength ranges constructed
using the cubepar reference file are slightly too long in some bands e.g., 3C.
The wavelength ranges were previously computed by looking at differences in min
max wavelength between slices but did not take into account tilts in the
isolambda across slices, a much smaller effect. The new MIRI MRS cubepar
reference file delivered here tweaks the wavelength ranges slightly to account
for this effect. This represents only a minor values change e.g., from 18.07 to
18.05 microns.
These new MIRI saturation files contain a single value for all the pixels,
including the reference pixels. The DQ flags are all set to zero. In fact, all
three detectors are set with the same value since there was no significant
difference in the files created for each detector separately using CV3 saturated
data. Previous versions of these files had different values per pixel which had
reflected the illumination pattern. These new files fix that problem by having
only a single value.
For the testing of Build 7.7, the MIRI RESET rmap needed to be updated to
reflect READPATT=N/A for all FASTGRPAVG cases - FASTGRPAVG8, FASTGRPAVG16,
FASTGRPAVG32, and FASTGRPAVG64. |

Activate a whole slew of changes necessary to bring up references and rmaps to be compatible with JWST 0.18, build 7.7. Changes include new FGS dark references, new NIRSpec APCORR and EXTRACT1D references, updated MIRI DARK, READNOISE, and FLAT rmaps, new MIRI APCORR references, new TWEAKREG step parameter references and new NIRISS LINEARITY and SATURATION references. |

These reference files are being removed because they have useafter dates one second older than the files which replaced them, causing them to become orphaned - active reference files that will never be used in calibration. |

Define all step parameter reftypes for all instruments.
The NIRSpec area, dflat, fflat, flat, fpa, and sflat rmaps were updated as part of the implementation of NRS_VERIFY as an exposure type. See JIRA issues CRDS-380 and JP-1423 for more information. |
