Rapid ASKAP Continuum Survey. V. 1367.5MHz
Listed in IVOA Registry (Virtual Observatory)
The Australian SKA Pathfinder (ASKAP) has surveyed the sky at multiple frequencies as part of the Rapid ASKAP Continuum Survey (RACS).
Description
The first two RACS observing epochs, at 887.5 (RACS-low) and 1367.5 (RACS-mid) MHz, have been released (McConnell, et al. 2020PASA...37...48M; Duchesne, et al. 2023PASA...40...34D). A catalogue of radio sources from RACS-low has also been released, covering the sky south of declination +30{deg} (Hale, et al., 2021PASA...38...58H).
With this paper, we describe and release the first set of catalogues from RACS-mid, covering the sky below declination +49{deg}. The catalogues are created in a similar manner to the RACS-low catalogue, and we discuss this process and highlight additional changes. The general purpose primary catalogue covering 36200 sq deg features a variable angular resolution to maximise sensitivity and sky coverage across the catalogued area, with a median angular resolution of 11.2"x9.3".

The primary catalogue comprises 3105668 radio sources, including those in the Galactic Plane (2861923 excluding Galactic latitudes of |b|<5{deg}), and we estimate the catalogue to be 95% complete for sources above 2mJy.
