||Affected data - NIRSpec, NIRSpec data with subarray=FULL, dark, mask and superbias reference files. NIRISS, all NIRISS modes, linearity and saturation reference files.
New NIRSpec darks, biases and masks were delivered for the affected data and were created from on orbit data taken between July 2022 and December 2022. These data are for an epoch prior to the last dark, mask and bias deliveries. New epochs for different readpatterns require that new dark, mask, and bias reference files be created to better calibrate all nirspec data taken between these dates.
NIRISS, all observing modes, linearity and saturation reference files. These new reference files no longer erroneously flag pixels as DO_NOT_USE after the linearity step and saturation step of the pipeline. Updated metrics based on statistical analysis are used to flag pixels where the linearity fitting is uncertain and to assign nominal values for these pixels in both the linearity and saturation reference files.
Reprocessing Info - Reprocessing for NIRSpec can wait until after the build 10.0 in early December 2023. NIRISS data should be reprocessed as part of the 12/5 batch reprocessing for the next pipeline build release.
||Affected data - MIRI, future MRS modes, mrsptcorr reference file. Delivering a new MIRI mrsptcorr rmap that includes a new reference file which contains a variety of correction factors relevant for point-source specific MIRI MRS observations. These correction factors include the fractional photometric response of the 12 micron spectral leak, and across-slice throughput and wavelength correction tables. This file is not used by versions 1.12.5 and earlier of the JWST pipeline, so this delivery is in support of ongoing development for future pipeline versions.
||New NIRSpec biases were delivered for all data taken after January, 1, 2023. These files were created from on orbit data taken between October 2022 and March 2023. The affected data are the NIRSpec FULL frame data taken with traditional readout or IRS2 readout.
||This nirspec barshadow file was delivered for use with Nirspec MOS data. A pipeline fix to increase the MOS y slit limits to add 2 pixels to the upper and lower edges of the slit, to include missing flux, resulted in the barshadow reffile introducing more noise because the file overcorrected the extended edges. This file corrects the problem but is still based on a model. Cycle 1 data is currently being analyzed and tested.
