The $\MC$~catalog also comprises: 241~sources which are not broad-line AGN; 34~sources which are spectroscopically classified as stars; 49~sources which are best-fitted with a stellar template and 14~sources for which the photometric redshift is not reliable.}
\tablefoottext{d}{According to Table~\ref{tbl-2} in \citet{salvato09}.}
\tablefoottext{e}{$R \leq 10$. \revsec{Radio loudness} is defined in Eq.~(\ref{radioloudness}). We exclude 51~radio-loud sources: 39~with spectroscopic redshift and 12~with photometric redshift.}
\tablefoottext{f}{All spectroscopically identified broad-line AGN are included, even if the classification is less than~19.}
