| 2026-08-05 | jwst_1590.pmap | latest | Affected data - All NIRCam WFSS and GRISM Time Series data, photom reference files. These new photom reference files contain updated flux calibration information for WFSS and Grism Time Series observations. These calibrations come from V14 of the sensitivity curves in the grismconf repository. The significant changes in this version compared to the previous are the flux calibration values for 2nd order spectra for the bluer filters - F250M through F360M. These files replace the recently delivered previous versions due to missing metadata entries for the photom and wavelength units. |
| 2026-08-04 | jwst_1589.pmap | archived | Affected data - All NIRCam WFSS and GRISM Time Series data, photom and wavelengthrange and specwcs reference files. These new photom reference files contain updated flux calibration information for WFSS and Grism Time Series observations. These calibrations come from V14 of the sensitivity curves in the grismconf repository. The significant changes in this version compared to the previous are the flux calibration values for 2nd order spectra for the bluer filters - F250M through F360M. This new NIRCam wavelengthrange file updates the wavelengths used when extracting spectra from WFSS and Grism Time Series data. The updated ranges in this file were derived from V14 of the sensitivity curves in the grismconf repository. Differences between this version and the previous version include significantly shortened long wavelength edges for 2nd order spectra in F322W2 and F356W, and a slightly shorter range for 1st order in F322W2. These updated specwcs reference files were created from V14 of the grismconf sensitivity curves and wavelength calibrations. These files represent an improved calibration from the data in the previous version of the reference files. Changes in these files relative to those from V13 include tweaks of the values corresponding to the trace endpoints, t0 and t1 values, and revisions to the 2nd order polynomial coefficients. |
| 2026-07-31 | jwst_1586.pmap | archived | Affected data - NIRSpec, full-frame BOTS, MOS, IFU, and FS modes, dark, mask, and superbias reference files. This is the FULL frame readout delivery for JWST Cycle 4 observations of DARK, MASK, and SUPERBIAS reference files. These files provide a set of independent non overlapping reference files which track the increasing population of hot pixels. We have now converted to using the STScI Python code which includes linearity correction of the DARK files. |
| 2026-07-23 | jwst_1584.pmap | archived | Affected modes - NIRISS, SOSS multistripe data, dark and superbias reference files. This delivery creates subarray-specific versions of the dark current reference file for the SUB680STRIPE_SOSS, SUB204STRIPE_SOSS, SUB60STRIPE_SOSS, and SUB17STRIPE_SOSS superstripe modes for NIRISS. Previously, all four of these subarrays were just using a copy of the SUBSTRIP256 dark current and superbias reference files. Removing NIRISS dark, 0235, and superbias, 0254, reference files from the active reference mapping to prepare for the delivery of multistripe subarray-specific dark and superbias reference files. 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_1584.pmap, to be used for processing and reprocessing of all JWST data upon installation of jwst version 3.0.0 into operations. |
