AllWISE Source Catalog (catalogs.allwise)

Description

The AllWISE Source Catalog contains astrometry and photometry for 747,634,026 objects detected on the deep AllWISE Atlas Intensity Images. A more detail description of the columns can be found here.

This table is cross-matched with Gaia DR2 gaia_source table through gaiadr2.allwise_best_neighbour reference table.
