JWST Galactic Center survey — brick

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

Full provenance for these renders: brick_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. Rendered from the v1.3-2026.08 mosaics, not v1.7-2026.09's.

4 color previews: one per pointing, and enough wavelength combinations that every band below appears in at least one. Rendered from the v1.3-2026.08 mosaics, not v1.7-2026.09's.

Multi-pointing / multi-epoch field. Each observation (o###) is a distinct pointing or epoch; images are grouped by observation. The combined catalog merges all observations (including ones whose images are not yet final and are held for a later release); per-observation catalogs are also provided.

Files are served from the JWST root Globus collection; downloading requires a free Globus login. Checksums and full provenance are in MANIFEST.json.

Detector-frame exposures

The 1200 individual exposures (131.5GB) the mosaics above were drizzled from, in the original detector frame, carrying the full distortion solution and this pipeline's astrometry as it stood before the images were resampled onto a sky grid. Each group holds exactly the frames behind the matching mosaic, taken from the record that mosaic itself carries of what went into it. Use these to re-drizzle, re-fit, or chase a per-exposure systematic.

0 of 2 registered observations are in this release. Absent, with nothing reduced for them when it was staged: o001, o004.

The last detector-frame product differs by field and filter: _crf is the Stage-3 outlier/CR-flagged frame where one was written, otherwise the _destreak / _align / _cal frame the mosaic was drizzled from directly. These are the pipeline's live products rather than frozen copies, so a re-reduction writes a new file beside them and a frame here can become an older generation than the pipeline now holds; they are not covered by CHECKSUMS.sha256. Each file records its own provenance in the keywords below, so a downloaded frame can be identified without reference to this page.

Globus transfer only for these frames. This field's data sit on a different filesystem from the release tree, so the frames are symlinked rather than hardlinked, and the Globus HTTPS data plane will not serve a symlink that points out of the release tree. Use the bundle button or globus transfer --recursive, which follow them; a browser or wget on a single frame URL returns 404. The mosaics, catalogs and tables above are unaffected.

The table ships as a frozen, checksummed copy; the detector frames do not, because a re-reduction rewrites their headers in place. This table, not the FITS, is what makes this version's astrometry reconstructible after the frames have moved on.

Where the two references differ, which one to believe is decided per filter by the contrast of the measurement rather than by a fixed preference — a sparse reference can have too few stars to place a peak at all. The bolded value is the one to quote. “neither” means the measurement is either too weak to cite or too large to be an accuracy figure, and the reason says which. Both columns are bulk offsets; a per-star error bar is a separate quantity.
