The Rapid ASKAP Continuum Survey V: cataloguing the sky at 1367.5 MHz and the second data release of RACS-mid
The Australian SKA Pathfinder (ASKAP) has surveyed the sky at multiple frequencies as part of the Rapid ASKAP Continuum Survey (RACS). The first two RACS observing epochs, at 887.5 (RACS-low) and 1367.5 (RACS-mid) MHz, have been released (McConnell et al., 2020; Duchesne et al., 2023). A catalogue o...

| description | The Australian SKA Pathfinder (ASKAP) has surveyed the sky at multiple
frequencies as part of the Rapid ASKAP Continuum Survey (RACS). The first two
RACS observing epochs, at 887.5 (RACS-low) and 1367.5 (RACS-mid) MHz, have been
released (McConnell et al., 2020; Duchesne et al., 2023). A catalogue of radio
sources from RACS-low has also been released, covering the sky south of
declination +30$^\circ$ (Hale et al., 2021). With this paper, we describe and
release the first set of catalogues from RACS-mid, covering the sky below
declination +49$^\circ$. 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 36 200 deg$^2$ features
a variable angular resolution to maximise sensitivity and sky coverage across
the catalogued area, with a median angular resolution of 11.2" times 9.3". The
primary catalogue comprises 3 105 668 radio sources, including those in the
Galactic Plane (2 861 923 excluding Galactic latitudes of $|b| |

estimate the catalogue to be 95% complete for sources above 1.6 mJy. With the
primary catalogue, we also provide two auxiliary catalogues. The first is a
fixed-resolution, 25-arcsec catalogue approximately matching the sky coverage
of the RACS-low catalogue. This 25-arcsec catalogue is constructed identically
to the primary catalogue, except images are convolved to a less-sensitive
25-arcsec angular resolution. The second auxiliary catalogue is designed for
time-domain science, and is the concatenation of source-lists from the original
RACS-mid images with no additional convolution, mosaicking, or de-duplication
of source entries to avoid losing time-variable signals. All three RACS-mid
catalogues, and all RACS data products, are available through the CSIRO ASKAP
Science Data Archive (CASDA).</description><identifier>DOI: 10.48550/arxiv.2311.12369</identifier><language>eng</language><subject>Physics - Astrophysics of Galaxies ; Physics - Cosmology and Nongalactic Astrophysics</subject><creationdate>2023-11</creationdate><rights>http://arxiv.org/licenses/nonexclusive-distrib/1.0</rights><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>228,230,780,885</link.rule.ids><linktorsrc>$$Uhttps://arxiv.org/abs/2311.12369$$EView_record_in_Cornell_University$$FView_record_in_$$GCornell_University$$Hfree_for_read</linktorsrc><backlink>$$Uhttps://doi.org/10.48550/arXiv.2311.12369$$DView paper in arXiv$$Hfree_for_read</backlink></links><search><creatorcontrib>Duchesne, S.
