Notes. The values have been obtained with combinations of SED fitting and post-processing. SED fits have been performed using MAGPHYS-PHOTOZ (Da Cunha et al. 2008; Battisti et al. 2019) for the median of Sect. 4.2.4 and CIGALE (Boquien et al. 2019) in all other cases. A long dash in a cell indicates that the corresponding value is either not available from literature or it does not have meaning in the model set-up used for the corresponding source.
