Table information for 'wise.main'

General

Table Description: This is the All-Sky source catalog, with several columns left out since we considered them to be only relevant for re-reduction, too arcane, or just because of a whim on our side. If you need them, let us know. The columns left out include: elon, elat, source_id, w?nm w?m, w?cov, w?cc_map_str, w?flux, w?sigflux, w?sky, w?sigsk, w?conf, w?mag_?, w?sigm_?, w?flg_?, w?magp, w?sigp1, w?sigp2, rho??, r_2mass, pa_2mass, n_2mass, [jhk]_m_2mass, [jhk]_msig_2mass, best_use_cntr, ngrp, x, y, z, spt_ind

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

The Wide-field Infrared Survey Explorer (WISE) is a space-based imaging survey of the entire sky in the 3.4 (W1), 4.6 (W2), 12 (W3), and 22 (W4) μm mid-infrared. This is the project's reliable Source Catalog containing accurate photometry and astrometry for over 500 million objects.

More details are available in the Explanatory Supplement, which also has a list of Cautionary Notes.

xscprox Ext. Prox. 2MASS Extended Source Catalog (XSC) proximity. This column gives the distance between the WISE source position and the position of a nearby 2MASS XSC source, if the separation is less than 1.1 times the Ks isophotal radius size of the XSC source. This identifies WISE sources that are identically the 2MASS XSC source as well as WISE sources that are fragments of large galaxies. deg N/A
tmass_key 2MASS id 2MASS PSC association. Unique identifier of the closest source in the 2MASS Point Source Catalog (PSC) that falls within 3" of the position of this WISE source. You can use this join to towmass.data, the pts_key column there. N/A meta.id.cross

Columns that are parts of indices are marked like this.
