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 |
|---|---|---|---|
| 2025-04-03 | jwst_1363.pmap | latest | 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. |
| 2025-03-24 | jwst_1361.pmap | archived | Affected data - NIRCam, DHS modes, dark, pars-detector1pipeline, readnoise, and superbias reference files. Delivered new imaps, pmap, and rmaps that define the new bkg and sirskernel reference types for NIRISS, and pictureframe and sirskernel reference types for NIRSpec. New bkg reference files were delivered and enabled to supersede the wfssbkg reference file type in Build 12.0, which will allow a single reference file type to be used for both SOSS and WFSS background correction reference files. New dark, readnoise, and superbias reference files for NIRCam DHS observations are being delivered to support pipeline processing of the initial in-flight observations using the new SUB41STRIPE1_DHS, SUB82STRIPE2_DHS, SUB164STRIPE4_DHS, and SUB260STRIPE4_DHS apertures. All pixels in the dark reference files are set to zero. Data in the readnoise and superbias files were extracted from existing full frame reference files, and therefore may not be the most accurate measure of the true readnoise or superbias levels. This NIRCam detector1pipeline parameter reference file specifies detector1 parameters for NIRCam DHS exposures. The jump step is on, but snowball flagging is turned off. Neighbor pixel flagging in the saturation and jump steps is left on, since both cases only affect immediate neighbors to bad pixels. New 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_13XX.pmap, to be used for processing and reprocessing of all JWST data upon installation of jwst version 1.18.0 into operations. |
| 2025-03-24 | jwst_1351.pmap | archived | Delivering a new MIRI mask rmap that sets NGROUPS to N/A for jwst_miri_mask_0067.fits. This file was previously delivered with this keyword missing, so NGROUPS was wrongly populated with UNDEFINED. |
