The minium angular distance between the radio matches and center of the galaxy (d_i) and the minimum of this distance weighted by the major axis (d_i/FWHM_i) for the 575 galaxies of our master catalog. These parameters were used to select the sample of potential radio emitting galaxies (Eq. (1)). We see that our cuts, d_i < max(2′,3 × FWHM_i) (dashed red lines), are not limiting the number of galaxies in the final sample.
