Catalogs: jicama.
Magnitudes are Vega. Built 2026-09-17 22:34 UTC.
Grid 60 hexagons wide.
Waiting on a band: o098 (needs F480M), o100 (needs F480M), o102 (needs F480M), o105 (needs F480M), o107 (needs F480M), o108 (needs F480M), o111 (needs F480M), o112 (needs F480M), o114 (needs F480M), o116 (needs F480M), o117 (needs F480M), o118 (needs F480M), o120 (needs F480M), o121 (needs F480M), o122 (needs F480M), o123 (needs F480M), o124 (needs F480M), o126 (needs F480M). These pointings have one filter reduced and not the other, so they carry no colour yet.
Mixed reductions. The pooled grey diagram combines fields from more than one reduction chain: plain — o106, o109, o125, o131, o133, o137, o138, o139; resbgsub — o127, o128, o129, o130, o132, o134, o135. resbgsub is residual-background-subtracted — a different reduction, not a later pass — so a colour offset between those fields and the rest would be a property of the processing, not of the sky.
Part of the tile: GC_106 (nrca), GC_109 (nrca), GC_133 (nrca), GC_138 (nrca). These pointings have no combined-module catalog yet, so only the listed NIRCam module is plotted — roughly 60% of the tile's sky, under the whole tile's name. Marked ⚠ in the table.
Quicklook, not a release. These are the catalogs that
exist right now, cross-matched between the two filters at
0.1″. They have not been through the
release gates, and the Treasury astrometry has no measured tie to
VIRAC2/Gaia yet.
