Notes. The separation reported is the offset between the optical and radio-source positions from the Legacy surveys and LoTSS-DR2 catalogue, respectively. It is important to note that the distances we report here were estimated from the spectral types and photometry and are therefore highly uncertain. The radio luminosities were derived assuming isotropic emission.
