||A new NIRSpec MSA operability file was delivered that includes the 3 shorts discovered in October 2022. This MSA operability file matches that now used in the PRD.
||New NIRSpec F flats and S flats created from in-flight data were delivered for all Fixed Slit and Bright Object data taken after launch. The F flats comprise the field-dependent throughput of the OTE and instrument FORE optics and the Sflats include the light path from the micro-shutter array up to but not including the FPA. These flats are for all grating/filter combinations except G140M/F100LP, because of time constraints during commissioning data was not taken for this grating/filter combination. Also, a new extract 1d reference file was delivered for Fixed Slits to include the correct aperture sizes for the flats to be applied in the pipeline.
||A new NIRISS persistence saturation reference file is being delivered. We discovered that the NIRISS persat reference file currently in CRDS jwst_niriss_persat_0003.fits is not properly scaled. The image values apparently were divided by the mean gain to convert from electrons to ADU when the reference file was created some years ago, but in fact the input image being used was already converted to ADU. As a result the image in extension 1 has been scaled back up by a factor of 1.612 in this delivery of the revised file. The other extensions have not been changed.
||Updated NIRCam distortion rmap to add the read pattern, NRC_CORON to the following files
The NIRCam Team recently found that the distortion files currently in CRDS for observations where one of the coronagraphic masks is used contain lists of exp_types that do not include NRC_CORON. The rmap was updated to fix that issue.
Additionally, the following files were removed from the rmap -
These files had been replaced with updated versions containing NRC_IMAGE in their list of read patterns.
