\caption{\label{multiband}Limiting   magnitudes   (3$\sigma$)  of   our   multiband
optical-to-IR photometry. $\it UBVRI$ values are derived either from the
{\it   WFI} observations or, when not  available, from the
{\it  GSC--2.3}  $B_{J},F,N$ equivalent (in  \textit{italics}).  $JHK$ values
are taken from {\it  2MASS}.   An hyphen indicates that no measurements
are   available.   The  last   column  lists   the  total   number  of
 objects per pointing after matching over all the passbands.}
