This is the CRDS Context currently in use by the pipeline calibration software.
Each cal version is associated - and guaranteed to work with - a specific build context. For JWST users, the default context is determined based on the version of JWST software you have installed, unless you explicitly override this by setting the "CRDS_CONTEXT" environment variable to a specific context or virtual context, e.g. "jwst-latest".Start Date | Context | Status | Description |
---|---|---|---|
2025-04-30 | jwst_1365.pmap | latest | This delivery improves the NIRISS WFSS-- GR150C and GR150R grisms-- background reference files for the F115W, F150W, and F200W filters. This delivery is needed as it better models detector regions of high-background level, and provides improved performance compared to previous reference files. The delivery also renormalizes the F090W GR150C and GR150R background reference files to be consistent with the other filters and provide 1 DN/s after flat-fielding. |
2025-04-08 | jwst_1364.pmap | archived | Replacement system_calver file for jwst software version 1.18.0, which corresponds to DMS Build 11.3. This file contains the new pinned context for Build 11.3, jwst_1364.pmap, to be used for processing and reprocessing of all JWST data upon installation of jwst version 1.18.0 into operations. |
2025-04-03 | jwst_1363.pmap | archived | A set of MIRI parameter reference files were delivered with tsovisit=N/A when they should have been delivered with tsovisit=false. A new set of reference files with the correct labels for tsovisit have been delivered, and so we are removing the mistake files for build 11.3. |
2025-04-03 | jwst_1362.pmap | archived | Affected data: MIRI, MIR_IMAGE, pars-outlierdetectionstep. These MIRI outlier detection parameter reference files are being delivered to add the good_bits parameter to all of the files so that any flats delivered with data in the LRS slit region do not leave residual NaNs in the combined i2d image. Bit values of DO_NOT_USE and NON_SCIENCE were flagged as bad pixels in these files so that outlier_detection did not use any region flagged as such as good pixels, resulting in the NaNs in the output combined images. This delivery also sorts out an issue found with previously delivered files that had tsovisit set to NA. The files should either have tsovisit set to True or False, which is fixed in this delivery. |
