| 2026-06-29 | jwst_1581.pmap | latest | Affected data - NIRSpec, MOS modes, pars-detector1pipeline reference file. MIRI, SUB256 and SUB128 modes, emicorr and rscd reference files. This NIRSpec delivery turns OFF the picture frame correction step in detector1 processing for NIRSpec MOS data for consistency with how data will be processed in MAST. Operational processing does not currently have access to MSA metadata files in detector1 and will skip the picture frame step regardless of whether it is turned ON. This delivery explicitly skips the picture frame step, so that default reprocessing will match data provided on MAST. Users may still find it beneficial to turn ON the picture frame corrections for MOS data if they perform custom reprocessing. When the MIRI team delivered updated EMICORR and RSCD files for the build 13.0 of the jwst calibration pipeline, they re-introduced issues that had been previously fixed with reference file tweaks. This delivery of the emicorr file removes the 10 Hz correction for SUB256 data, as the correction is close in phase to the subarray and in some cases, applying the correction led to large stripes in the rate files. This tweak to the RSCD file sets the SUB128 array to skip only the first group for the first integration and 2 groups for all other integrations rather than using 7 groups for all integrations. This should be a temporary update, with the hope that new darks created with the EMICORR step applied should avoid the emi noise showing up in short ramp data due to the skipping of too many frames with the RSCD step. These changes set the files back to the versions currently in use by the pipeline and do not require reprocessing for any data by the users. New system_calver file for jwst software version 3.0.0, which corresponds to DMS Build 13.0. This file contains the pinned context for Build 13.0, jwst_1581.pmap, to be used for processing and reprocessing of all JWST data upon installation of jwst version 3.0.0 into operations. |
| 2026-06-24 | jwst_1578.pmap | archived | New system_calver file for jwst software version 3.0.0, which corresponds to DMS Build 13.0. This file contains the pinned context for Build 13.0, jwst_1578.pmap, to be used for processing and reprocessing of all JWST data upon installation of jwst version 3.0.0 into operations. |
| 2026-06-22 | jwst_1577.pmap | archived | Affected data are NIRSpec FS allslits subarray data. These NIRSpec dark and bias files were delivered because time dependent changes in the instrument, increased hot pixel populations and elevated signals in the neighboring pixels, require new epochs of dark and superbias reference files to better calibrate all NIRSpec science data taken after 19 March 2026. |
| 2026-06-18 | jwst_1576.pmap | archived | Affected data are all NIRSpec IFU, MOS and FS data, and MIRI MRS bad pixel files for MIRI data taken after April 20, 2026. For NIRSpec fixed slit data, the pars-spec2pipeline parameter reference file enables the clean_flicker_noise step in the spec2 pipeline improving the flicker noise removal on the final extracted spectra. For full-frame NIRSpec fixed slit, IFU, and MOS data, the pars-detector1pipeline parameter reference files enable the picture_frame step to correct for the thermal picture frame effect that is present on NIRSpec data. This delivery also includes new MIRI MRS bad pixel reference files for Winter 2026 with a use after date of 04-20-2026. Shallow observations, defined as FASTR1 data with NGROUPS less than 50, use the least aggressive bad-warm pixel masking. Medium-depth observations, defined as FASTR1 data with NGROUPS greater than or equal to 50, use a slightly more aggressive flagging. Deep observations, defined as all SLOWR1 data, use the most aggressive flagging thresholds. This hybrid scheme is designed to help flag known bad pixels at the level actually required by different science cases. Each of the new bad pixel masks is based upon a thresholding analysis of multiple deep MRS background sky observations. We are also delivering a new Badpixel mask for FASTGRPAVG8. Currently using the same deep-observation mask as used for SLOWR1. |
