Table 4: Limiting magnitudes (3$\sigma $) of our multiband optical-to-IR photometry. $\it UBVRI$ values are derived either from the WFI observations or, when not available, from the GSC-2.3 BJ,F,N equivalent (in italics). JHK values are taken from 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.
