JWST Globular Clusters — m4

Release v1.1-2026.07 · built 2026-07-12 · ← all fields

4 withheld as bad astrometry. The pipeline repudiated the mosaics these were staged from -- the m2 astrometry checkpoint corrected the offsets table and quarantined every mosaic built before it: F150W2, F322W2. They will return when the field is re-staged from current products.

Catalogs

No catalogs in this release. Photometry for these data is still being produced; when it is ready it will be added here under a new version.

Astrometric provenance

This field has no registered pointing correction. It is absent from the pipeline's alignment registry, so no per-exposure correction was applied and these products carry the raw assign_wcs astrometry. Do not assume they are tied to Gaia or VIRAC2. (A field in this state shipped mosaics ~14.8″ off before it was noticed.)

2 reference-tie measurement(s) exist for this field, and none is shown here: they are not attached to what this version ships — either the version carries no pointing-correction table, or the measurements postdate the release. A later version's page carries the ties that describe it.
