\tablefoot {Emission-line fluxes are reported both as observed and (between square brackets) corrected for the intervening Galactic absorption~\mbox{$E(B-V)_{\rm Gal}$} along the object line of sight (from Schlegel et~al. \cite{Schl98}). Line fluxes are in units of 10$^{-15}$~erg~cm$^{-2}$~s$^{-1}$, whereas X-ray luminosities are in units of 10$^{43}$~erg~s$^{-1}$ and the reference band (between round brackets) is expressed in~keV. The typical error in the redshift measurement is $\pm$0.001 
but for the SDSS and 6dFGS spectra, for which an uncertainty of $\pm$0.0003 can be assumed.}
