JWST Galactic Plane fields — w51

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: F140M, F162M, F182M, F187N, F210M, F335M, F360M, F405N, F410M, F480M. 2 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: F150W, F444W. They will return when the field is re-staged from current products.

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.

No mosaics in this release. Nothing resampled onto a sky grid is distributed here. See the release README for what this version contains.

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 2026-11-10T10:27Z; the full list is in the HiPS index and hips_inventory.json.

Tours of this field

• W51 wavelength explorer (linear)
• W51 wavelength explorer, stars subtracted (linear)
• W51 wavelength explorer (other)
• W51 wavelength explorer
• W51 star-forming region tour

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

Open the catalog manifold viewer prototype 174,641 stars from W51 NIRCam photometry. Built from the v1.0-2026.06 catalog files; it can differ from the catalog files listed below. WebGL; best on a desktop GPU.

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.

15 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.
