Notes. Cols. (1)–(3): name and coordinates of the source; Col. (4): type of dropout and survey the source was selected from, in brackets; Col. (5): spectroscopic redshift. The † symbol indicates sources whose redshift was estimated based on the fit of an emission line; Col. (6): peak flux density at 888 MHz from the RACS source lists. The ‘*’ indicates flux densities at 944 MHz from EMU; Col. (7): z-band magnitude from DES or Pan-STARRS, depending on the survey from which the source was selected; Col. (8): dropout r − i or i − z depending on the type of dropout in Col. 4; Col. (9): z − W2 colour, where z is the magnitude in the z filter (from DES or Pan-STARRS) in the AB system and W2 is in the Vega system; Col. (10): radio-to-optical distance; Col. (11): telescope used for the identification.
