Affected data - NIRSpec, full frame modes, dark and superbias reference files.
Updated NIRSpec dark and superbias reference files were delivered for NRS1 and NRS2 full frame traditional readout modes with useafter March 1, 2023, and NRS1 and NRS2 IRS2 readout modes with useafter April 1, 2023. These new files were created from on orbit data taken during Cycle 1 under PID 1484 using snowball removal. |

Affected data - MIRI, all modes, pars-emicorrstep reference files. NIRISS, AMI modes, NRM and throughput reference files.
These emicorr parameter reference files are the first parameter reference files for the emicorr step, and will control which data uses the emicorr step and which data skips the step, based on the readout pattern. The code for the emicorr step will be part of the build 10.1 install, but this file will control the usage as of build 10.2 installation. This is the first delivery of the new NRM reference file. It is being delivered to avoid introducing a WebbPSF data file dependency with the AMI processing changes to be made in pipeline build 10.2. This file contains a numerical model of the seven hole pupil mask that enables AMI mode. More details of its creation and validation are in JWST-STScI-007417. These NIRISS throughput files contain throughput data for the four NIRISS AMI filters at a more finely sampled wavelength interval than the previous throughput files. The throughput values were derived from the ETC/Pandeia throughput files provided by Kevin Volk. The throughput combines the telescope and internal optics throughputs, filter response, the detector quantum efficiency, and the photon yield. The throughput is then normalized to unity. |

This delivery corrects an erroneous FFLAT file for MOS G235H that caused up to 300 percent flux errors for wavelengths longer than 2.25 microns. |

A mistake was found in the previous MIRI emicorr reference file for the BRIGHTSKY subarray. The values for frame and row clocks were incorrect for the BRIGHTSKY subarray, and have been corrected in the updated file. This reference file will be needed for a proper correction to the BRIGHTSKY data, and the data for that subarray should be reprocessed. |
