Table 3: \ensuremath {\gamma }-ray rate predictions from simulations for the standard, hard and 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 \ensuremath {^{\circ }} (the usual observing mode). The cut selection efficiencies and (peak rate) energy thresholds in each case are also given.
