Rapid ASKAP Continuum Survey. II. RACS cat.

The Rapid ASKAP Continuum Survey (RACS) is the first large sky survey using the Australian Square Kilometre Array Pathfinder (ASKAP), covering the sky south of +41{deg} declination. With ASKAP's large, instantaneous field of view, ~31{deg}^2^, RACS observed the entire sky at a central frequency of 887.5MHz using 903 individual pointings with 15 minute observations. This has resulted in the deepest radio survey of the full Southern sky to date at these frequencies. In this paper, we present the first Stokes I catalogue derived from the RACS survey. This catalogue was assembled from 799 tiles that could be convolved to a common resolution of 25", covering a large contiguous region in the declination range {delta}=-80{deg} to +30{deg}. The catalogue provides an important tool for both the preparation of future ASKAP surveys and for scientific research. It consists of ~2.1 million sources and excludes the |b|<5{deg} region around the Galactic plane. This provides a first extragalactic catalogue with ASKAP covering the majority of the sky ({delta}5deg (RACS_DR1_Sources_GalacticCut_v2021_08))
