A Catalog of Very Large Array Sky Survey Epoch 1 Quick Look Components, Sources, and Host Identifications

Abstract

Abstract We announce here the public availability of a catalog of ν ∼ 3 GHz Quick Look observations from the first epoch of the Very Large Array Sky Survey. The catalog consists of three distinct and linkable tables, namely (a) the detected radio components, (b) the host identifications with total source properties for single-component, and close double/triple radio sources (angular separations of <10″), and (c) the Quick Look image metadata. Given the Quick Look images are limited in quality, we include data reliability flagging to improve the scientific usability of this catalog. Using our recommended quality flags, this catalog contains 1.7 × 10 6 unique radio components with S 3 GHz ≳ 1 mJy beam −1 , and 6.2 × 10 5 host IDs (including 20,000 close-double and triple radio sources) reliably detected across the entire sky at δ > −40°. The catalog and an associated User Guide have been produced as part of the Canadian Initiative for Radio Astronomy Data Analysis, and are available at https://cirada.ca/catalogues .
