JWST Calibration Reference Data System (CRDS)

 

NOTICE

The term "operational" has changed to "latest" when referring to the newest CRDS Context available. For more information, please refer to the user guide.

Documentation updates are ongoing. If something in the user guide is ambiguous, please reach out to the CRDS team or file a help desk ticket.


Build Context: jwst_1413.pmap based on CAL Version: 1.19.1

This is the CRDS Context currently in use by the pipeline calibration software.

Build Context Table

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".

Context History (more history, all contexts, build contexts)

Start Date Context Status Description
2025-11-05 jwst_1466.pmap latest New system_calver file for jwst software version 1.20.2, which corresponds to DMS Build 12.1.1. This file contains the pinned context for Build 12.1.1, jwst_1464.pmap, to be used for processing and reprocessing of all JWST data upon installation of jwst version 1.20.2 into operations. Deleted system_calver file 0053 because a new file that will cover cal versions 1.20.1 and 1.20.2 will be delivered.
2025-10-23 jwst_1464.pmap archived New system_calver file for jwst software version 1.20.1, which corresponds to DMS Build 12.1. This file contains the new pinned context for Build 12.1, jwst_1464.pmap, to be used for processing and reprocessing of all JWST data upon installation of jwst version 1.20.1 into operations.
2025-10-23 jwst_1463.pmap archived Affected data. MIRI flats update affect only LRS TA data. This delivery of MIRI imager flat files updates the DQ, data quality, values for the LRS slit region. It was recently discovered that the LRS TA verification images had NaN values in the LRS slit region, and this update makes those pixels usable again. The previous flat file delivery listed the DQ values for the LRS slit region as both NON_SCIENCE and DO_NOT_USE, but this ends up masking the LRS slit region for all uses of the flat file. This update changes the DQ values for the specified region to be only NON_SCIENCE, removing the DO_NOT_USE flag. The science pixels are not changed from the previous version, so there is no need to reprocess any data except for cases like TA verification where the imager flats would be used and need to show the LRS slit region.
2025-10-09 jwst_1462.pmap archived Affected data - MIRI data, detector MIRIMAGE, photom file. This MIRI imager photom file is being updated because during pipeline testing, a bug was found with the SUBARRAY values in the imager photom file, such that the flux values from the new pipeline version 1.20.0 using the updated photom file were giving unexpectedly high percent differences from the previous versions. These differences were tracked to a bug in the code that created the reference file. The bug has been fixed, and the reference file updated to bring the subarray differences in line with the full frame array differences. Data for the MIRIMAGE detector should be reprocessed with this file. Also delivered new system_calver file for jwst software version 1.20.0, which corresponds to DMS Build 12.1. This file contains the new pinned context for Build 12.1, jwst_1462.pmap, to be used for processing and reprocessing of all JWST data upon installation of jwst version 1.20.0 into operations.
