JWST Galactic Plane fields — wd2

7 withheld as superseded. The sources these were staged from are no longer the files they were copied from -- they have been rebuilt or replaced since, so these are the older bytes. Why is not recorded here, and no claim is made about their astrometry: F150W, F162M, F164N, F187N, F212N. 3 withheld: source no longer on disk. The mosaics these were staged from are not where the release recorded them, so the staged copies cannot be re-verified against anything. Why they are gone is not recorded here: F444W. They will return when the field is re-staged from current products.

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

Full provenance for these renders: wd2_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.

2 color previews: one per pointing, and enough wavelength combinations that every band below appears in at least one.

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

Mosaic images (resampled onto a sky grid)

Open the color wavelength tour Aladin Lite view of the mosaics; the slider steps through color images of three neighboring filters, from the shortest wavelengths to the longest.

HiPS sky maps

Hierarchical (HiPS) renderings of this field's mosaics, for Aladin Lite, Aladin Desktop, or any HiPS client: paste the HiPS URL, or open the layer directly. Served layers as of 2026-11-08T10:27Z; the full list is in the HiPS index and hips_inventory.json.

Tours of this field

Views across several fields

• All Aladin Lite tours Every tour and wavelength explorer, including the linear wavelength tours.
• Index of all release HiPS Every HiPS layer made from the release fields, grouped by field.

Catalogs

Preliminary catalog release. The field-wide merged photometry table is still being built; only the per-filter vetted catalogs are provided for now. The merged table will be added in a later update.

Column descriptions (text) What each catalog column means, with units and flag values.

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.)

1 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.
