Stacked PSFs by Field¶
Processing Versions¶
NIRCam¶
v1.0: Based on the CEERS NIRCam pipeline, with improved WCS calibration and background subtraction.
v1.1: Move the WISP and 1/f correction steps to Stage 2 to allow persistence masking between pipeline stages.
v1.2: Improve the 1/f correction by setting the stripe correction to zero for any row or column in which more than 85% of the pixels are masked. Also improve outlier clipping.
v1.3: Build a reference catalog from F814W and F160W and use it to create the F150W image. Then build a second reference catalog from F150W and F160W to process NIRCam data in the remaining bands.
v1.4: Improve outlier clipping and build the first UDS reference catalog from UKIDSS, F814W, and F160W. Subsequent calibration follows the v1.3 procedure.
v1.4.1: Correct WCS issues in COSMOS and UDS for F090W, F115W, and F200W.
v1.5: Introduce a new WISP subtraction algorithm (currently not applied to the data), update the WISP template, improve mask construction for 1/f removal and background processing, improve outlier clipping, correct a bug in readout-noise construction, and resolve background issues in the files used for the final drizzle.
v1.6: Improve readout-noise treatment and add masks for several outlier regions.
v1.7: Expand the processed dataset to include all observations available as of August 25, 2026. Add a dedicated diagonal-stripe removal procedure for affected exposures, which substantially suppresses the striping artifacts while preserving the underlying science signal. Faint residuals may still be visible in a few strongly contaminated exposures.

v1.7: JWST calibration pipeline v1.16.1; CRDS pmap 1321
MIRI¶
v1.0: Based on the CEERS MIRI pipeline and the JWST-SPRING NIRCam v1.1 pipeline.
v1.1: Fix a bug that prevented model.meta.wcs, model.meta.wcsinfo, and model.meta.cal_step.tweakreg from being updated in the data model after WCS calibration.
v1.2: Following the NIRCam v1.4 procedure, build a reference catalog from F444W and F160W for MIRI WCS calibration.
v1.3: Correct WCS calibration issues in the pipeline.
v1.3.1: Correct the WCS issue in COSMOS and UDS for F770W.
v1.4: Improve flat-image construction for the detection, DQ, and error arrays; update the strategy to create a flat image every six months; and add an outlier-masking step.
v1.5: Replace flat-file construction with a super-background approach.
v1.7: Expand the processed dataset to include all observations available as of August 25, 2026. Version v1.6 was intentionally skipped to keep the MIRI version numbering consistent with NIRCam.
