Affected data- MIRI, all modes, pars-jumpstep files. NIRCam, all modes, pars-jumpstep and photom files. NIRISS, all modes, pars-jumpstep files. NIRSpec, all modes, pars-jumpstep files.
Due to issues found in processing some JWST data with the new cosmic ray snowball and shower code, the decision was made to temporarily turn off this code. These updated jump step parameter reference files for MIRI, NIRCam, and NIRSpec will turn off this step. The data in MAST will be reprocessed with this file, and if users want to turn off the snowball and shower code, they can use this parameter reference file to re-run their own data.
Delivering a previous version of the NIRISS pars-jumpstep rmap that does not include the most recent pars-jumpstep files delivered after build 9.1.1. Issues were found with the snowball correction algorithm implemented in build 9.1.1, so a new pars-jumpstep rmap is being delivered to temporarily back out the affected files while developers work on a fix.
Update to the MIRI pars-jumpstep rmap to add DETECTOR and TSOVISIT as selection criteria.
These NIRCam photom files contain updated flux calibration values and curves for WFSS and Grism Time Series observations. These are updated flux calibration curves derived from flight data for these modes. The calibration curves in these files have a higher resolution than those in the previous version. In addition, updated F250M and F277W curves have been included. In previous files, the calibration curves for these filters were derived from ground based data. These have useafter dates set to 2014, and are intended to be used with all NIRCam WFSS and Grism Time Series data. These files will replace the previous reference files, which had lower resolution calibration curves. |

Modes Affected NIRSpec data with exptypes nrs fixedslit or nrs brightobj and subarray s400a1 or allslits. A new NIRSpec pathloss reference file was delivered for all fixed slit and bright object data using the S400A1 or allslits subarrays. This is the first time pathloss information for S400A1 is being delivered to CRDS and is model based. Inflight pathloss information for all modes based on commissioning data will be delivered to CRDS soon. |

Delivering new MIRI, NIRCam, NIRISS, NIRSpec pars-jumpstep rmaps that include the pars-jumpstep reference files that were previously causing issues with the snowball algorithm incorporated in JWST build 9.1.1. The patch 9.1.2 is being installed to fix these issues, so the previously delivered pars-jumpstep files can now be activated. |

Affected data - NIRCam, WFSS and Grism Time Series, photom
These NIRCam photom files contain updated flux calibration values and curves for WFSS and Grism Time Series observations. These are the first flux calibration curves derived from flight data for these modes, and represent a significant improvement over the previous, ground based files. They have useafter dates set to 2014, and are intended to be used with all NIRCam WFSS and Grism Time Series data. These files will replace the previous, ground based photom reference files. |
