$^{\rm 1}$ The percentages are computed over the number of galaxies for each morphological subsample; $^{\rm 2}$ number of galaxies in the total samples or the morphological subsamples; $^{\rm 3}$ F3: factor 3 radio excess; F5: factor 5 radio excess. Figures given in percentages; $^{\rm 4}$ all percentages for the fraction of radio-excess galaxies are upper limits as explained in Sect. 4.1.3.
