\caption{\gr\ rate predictions from simulations for the standard, \emph{hard}
 and \emph{loose} selection cuts. This table is valid for a~source with an~energy spectrum similar to the Crab, for observations at an~offset of~0.5\dg\ (the usual observing mode). The cut selection efficiencies and (peak rate) energy thresholds in each case are also given.}
