(\cite{Chapman2005}); irAGN or irSFR denotes whether the source has been classified as a star-forming galaxy or an AGN~according to the IR-SED fit; oAGN or oSFR denotes that the source has been classified as an AGN or a starburst according to the optical spectrum of Chapman et~al. (\cite{Chapman2005}); $\dagger$: luminosity from Chapman et~al. (\cite{Chapman2005}). \end{table}
