\begin{table}%t3 \par %\centering \par \caption{\label{line-strength}Line-strength indices in our sample of red-galaxies with $S/N$(\AA)~$>$~10 and no- or weak-emission lines. The number between brackets after the indices values indicates the presence (1) or not (0) of sky-subtraction residuals or telluric absorptions inside the definition passband of the index. Only those indices with labels (0) are used in our analysis. Type: Indicate the presence (2) or not (1) of weak ($\rm [OII]<7$~\AA) emission lines. Last column lists the measured velocity dispersion and its error. This is only a portion of the table, shown for guidance regarding its format and content.
