| 2026-05-15 | jwst_1544.pmap | latest | Data affected - MIRI, imager data, source catalog parameter reference file. The wide-field slitless modes of the JWST instruments need the source catalog to use segmentation maps with deblend set to True. The imager group agreed that deblending would be beneficial in most cases, so the MIRI source catalog parameter reference files are being updated to add the parameter deblend equal True. This will affect all MIRI imager data, but users do not need to re-run the pipeline with their data. |
| 2026-05-14 | jwst_1543.pmap | archived | Data affected - All MIRI fast mode readout pattern data. Updated readnoise files for MIRI fast mode data A new set of MIR readnoise files are necessary due to plans for FASTGRPAVG8 readout mode replacing SLOWR1 mode in the near future. The new FASTGRPAVG8 files average 8 groups before creating the readnoise file. In the process of creating these new files, it was discovered that the previous files were created using a refpix step in the pipeline that MIRI no longer uses. So FASTR1 files for all three detectors are also being updated, with the refpix step being skipped. Those differences would be very small and not noticeable in the output of detector1, so there is no need for users to reprocess their data with the FASTR1 files. jwst_miri_readnoise_0057.fits was removed to prevent conflicts with new files which split FASTGRPAVG8 from the other FAST options. |
| 2026-05-13 | jwst_1541.pmap | archived | Affected data - MIRI TSO data calwebb_detector1 parameter reference file. This updated MIRI TSO calwebb_detector1 parameter reference file is being updated to fix a typo in the parameter description. The step name under the class description for the JumpStep class had a name of refpix, which has now been updated to jump. Removing jwst_miri_readnoise_0085.fits to prepare for new files which split FASTGRPAVG8 from the other FAST options. Removed to prevent a conflict. |
| 2026-05-12 | jwst_1539.pmap | archived | Affected Data: MIRI parameter reference file for TSO data in detector1. This MIRI parameter reference file for TSO data being run through calwebb_detector1 removes any reference to the firstframe step which is deprecated in build 12.3 and will be removed in build 13.0. This is simply to ensure that the pipeline will not crash with a reference to a step that no longer exists. No data will need to be reprocessed. |
