\begin{table}%t4 \caption {\label{zzsum} Summary of \zphot accuracy achieved for the whole low-$z$ and high-$z$ samples with {\it Hyperz} and GR~codes.} \include {10644_t2} \par \smallskip Notes: results for type 1 and type~$1+2$ spectroscopic data are presented in this table, as well as the accuracy reached for the different spectral types of galaxies in the whole sample (i.e. all type~1, 2 and~3 redshifts). The information given is the same as in Table~\ref{zz}. \end{table}
