TL;DR
The CatWISE2020 Catalog provides an extensive, improved all-sky infrared source dataset with increased depth, accuracy, and source count, based on six years of WISE/NEOWISE data and advanced detection methods.
Contribution
It presents a significantly expanded and more accurate all-sky infrared catalog using new detection software and six years of data, surpassing previous catalogs in depth and precision.
Findings
Contains 1.89 billion sources over the entire sky.
Achieves 90% completeness at W1=17.7 mag and W2=17.5 mag.
Provides proper motion accuracy of 20 mas/yr for bright sources.
Abstract
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 m (W1 and W2) collected from 2010 Jan. 7 to 2018 Dec. 13. This dataset adds two years to that used for the CatWISE Preliminary Catalog (Eisenhardt et al., 2020), bringing the total to six times as many exposures spanning over sixteen times as large a time baseline as the AllWISE catalog. The other major change from the CatWISE Preliminary Catalog is that the detection list for the CatWISE2020 Catalog was generated using (Schlafly et al. 2019), while the CatWISE Preliminary Catalog used the detection software used for AllWISE. These two factors result in roughly twice as many sources in the CatWISE2020 Catalog. The scatter with respect to photometry at faint magnitudes in the COSMOS field, which is out of the…
