These MIRI gain files were generated to reflect the most recent analysis of the gain values for all MIRI detector configurations. Any changes will be minimal and no data needs to be specially reprocessed. |

NIRISS, imaging, tweakreg step parameter files. These new files change the SEPARATION parameter to avoid an error in the version 1.15 data reduction pipeline. The value has been made larger than the THRESHOLD parameter as is required. |

NIRISS, AMI mode, charge migration step parameter reference files. The signal threshold has been revised for each AMI filter according to Goudfrooij et al. 2024 PASP, 136, 014503 in order to minimize the effects of charge migration on calibrated data. Data from program 1509 with NRM pupil and F480M filter at AMI primary dither position 1 were used to derive the new signal limits. |

Modifications were made to the high resolution gratings G235H G395H G140H and PRISM IFU SFLAT reference files with the goal of improving the quality of the science data. Noise levels on the edges of the IFU slices have been decreased by flagging pixels with unreliable flat field data as ones, and pixels with no flat field data and low throughput values are now set as DO NOT USE or NaNs. The NIRSpec Team recommends users to reprocess the affected IFU data to see the improvements reflected in their final data cubes. |
