Notes. Column 1: target name. Column 2: spectroscopic redshift from Ahn et al. (2012) (for the Double and the Original TRG) and Alam et al. (2015) (for the Goldfish, the Beaver, and the Embryo). Column 3: host galaxy coordinates from Alam et al. (2015) (for the Double) and Gaia Collaboration (2021) (for all the others). Column 4: radio morphological classification following Fanaroff & Riley (1974) (FRI/FRII) and Miley (1980) (NAT/WAT). Column 5: robust parameter used for Briggs weighting during imaging. Column 6: beam size. Column 7: rms noise.
