\tablefoot{The six-digit number given
 in the second column is the mask identifier as given in the image
 header (keyword: \texttt{HIERARCH ESO INS MASK~ID}). The seeing
 values (Col.~6) were determined from the acquisition images taken just before
 the MXU exposures. The numbers given in Cols.~7 and~8 refer to the total number of slits and the number of GCs found on a given mask, respectively.}
