TABLE  catwise_2020

This table contains the parameters provided for each source in the CatWISE 2020 Source Catalogue. The CatWISE2020 Catalog consists of 1,890,715,640 sources over the entire sky selected from WISE and NEOWISE survey data at 3.4 and 4.6 microns (W1 and W2) collected from 2010 Jan. 7 to 2018 Dec. 13. This dataset includes six times as many exposures and spans over sixteen times as large a time baseline as the AllWISE catalog. CatWISE adapts AllWISE software to measure the sources in co-added images created from six-month subsets of these data, each representing one coverage of the inertial sky, or epoch. CatWISE2020 includes the measured motion of sources over the 8 year span of the data, typically in 12 epochs. The scatter with respect to Spitzer photometry at faint magnitudes in fields out of the Galactic plane and at low ecliptic latitude (corresponding to lower WISE coverage depth) is similar to that for the CatWISE Preliminary Catalog, reaching 0.217 mag (equivalent to SNR 5) at approximately W1=17.7 and W2=16.5, vs. W1=16.9 and W2=15.9 for AllWISE. The 90% completeness depth for CatWISE2020 is at roughly W1=17.7 and W2=17.3, about 1.7 mag deeper than in the Preliminary Catalog. From comparison to Gaia, the motions are over a dozen times more accurate than those from AllWISE. Required constraints: Primary key is (source_id)
