Notes. Columns: Source name in LoTSS DR2; host galaxy name in CLU; projected offset between the radio source and Hα source coordinates in arcsec, and corresponding transverse distance in parsec; redshift (z), with distance method indicated in parentheses: (k) kinematic; (m) median (redshift-independent), (n) narrowband (Hα); star formation rate (logSFR); radio luminosity at 144 MHz (log L); standard deviation (σ) above the L-SFR relation; radio spectral index (α; Sect. 3.2); radio loudness Rg (Sect. 4). Sources with spectral line measurements in SDSS table galSpecLine (Sect. 3.1; Tremonti et al. 2004; Brinchmann et al. 2004) have their redshifts marked in bold. Candidates below and above an offset value of (2 + ϵ)″ are demarcated with a solid line, with ϵ being the LoTSS astrometric uncertainty. The third (bottom) section includes candidates in the AGN region of Fig. 1.
