Notes. These data come from Tables 1 and 2 of Falgarone et al. (2017), except for the bolometric luminosity (Ivison et al. 2010). By conservation of energy, the line and continuum flux densities, Fν, have been derived from the observedflux densities, 
, as 
. This flux density is what would be observed from a source located, in a Euclidean space, at the angular diameter distance DA derived from the Planck cosmological parameters (Planck Collaboration VI 2020).
