Astrometrically corrected catalogues of the Rapid ASKAP Continuum Survey - Low epochs

These catalogues provide the corrected astrometry for the RACS-Low1 epoch of the Rapid ASKAP Continuum Survey (McConnell et al. 2020, https://data.csiro.au/collection/csiro:52217), incorporating the methodology presented in the paper "Enhanced Astrometry of the Rapid ASKAP Continuum Survey for Precise Localisation of Fast Radio Bursts (Jaini et al. 2025)". The dataset includes two catalogues: the corrected all-sky source catalogue and the corresponding Gaussian component catalogue, mirroring the structure and format of the original release. All original header metadata is retained, with additional or updated columns to reflect astrometric corrections.

'ra', 'dec': Corrected Right Ascension and Declination (J2000) values
'ra_old', 'dec_old': Original uncorrected RA and Dec values
'e_ra', 'e_dec': Corrected 1-σ positional uncertainties in RA and Dec
'e_ra_old', 'e_dec_old': Original positional uncertainties
'gal_lat', 'gal_lon': Corrected Galactic Latitude and Longitude
'gal_lat_old', 'gal_lon_old': Original Galactic coordinates

These catalogues can be accessed by querying the Data Central TAP service at https://datacentral.org.au/vo/tap. Documentation for this service can be found at https://docs.datacentral.org.au/reference/services/tap-service/.
