\caption{Number of spectra in different magnitude sub-samples. Bright
 and faint galaxies correspond to objects with $ M_{R_{\rm AB}}<-20$ and $
 M_{R_{\rm AB}}>-20$ respectively. Bright objects correspond to the same
 sampling in absolute magnitude as in the MORPHS spectroscopic
 catalogue (Dressler et~al. \cite{Dressler99}). \label{tab:spectra}}
