JWST Galactic Center survey — sgrb2

Release v1.1-2026.07 · built 2026-07-11 · ← all fields

10 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: F150W, F182M, F210M, F212N, F300M, F360M, F405N, F410M, F466N, F480M. They will return when the field is re-staged from current products.

Curated colour images -- the published renders. Tuned stretches, channels chosen far apart, and each program combined with itself.

Full provenance for these renders: sgrb2_curated.json -- source path and checksum, the checksum of the bytes served, and whether the AVM astrometry survived resizing. These are curated renders, not staged data products; the mosaics they were made from are in the table below.

Automatically generated previews, one per pointing and enough wavelength combinations that every released band appears in at least one.

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 release version does not ship a pointing-correction table. The field has one, but it was not staged with this version, so nothing here describes the solution these products were built on.

11 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.
