\begin{table}%t3 \caption {\label{zz}Summary of \zphot accuracy achieved for the individual low-$z$ and high-$z$ clusters.} \include {10644_t1} Notes: the information given in this table is: (1) cluster identification, (2) filter set used to compute $z_{\rm phot}$, (3) spectroscopic $z_{\rm cluster}$, (4) $E(B-V)$ at the cluster center, (5) total number of redshifts available in the field, (6) total number of spectroscopic redshifts used for accuracy determinations, and \zphot accuracy achieved with {\it Hyperz} and GR codes: (7) (13) systematic deviation between \zphot and $z_{\rm spec}$, (8) (14) standard deviation $\sigma_z$, (9) (15) median absolute deviation ($\sigma_{z,\rm MAD}$), (10) (16) normalized median absolute deviation ($\sigma(\Delta z/(1+z))$), (11) (17) fraction of catastrophic identifications~($l\%$), (12) (18) fraction of spurious identifications~($g\%$). Clusters excluded in the computation of the averaged accuracy are given in italic (see text). The spectroscopic $z_{\rm cluster}$ in Col.~(3) corresponds to the most prominent cluster in the field. Other clusters have been identified in cl1037 ($z=0.578$), cl1103 ($z=0.959$ and 0.626), cl1138 ($z=0.455$), cl1227 ($z=0.583$), cl1301 ($z=0.397$), and cl1354 ($z=0.595$) (see Milvang-Jensen et~al.\ \cite{MilvangJensen08}, for details). \end{table}
