+The GC culminates at about 58 deg ZA in La Palma. Below 60 deg ZA, it is visible between April and late August for about 150 hours. The GC has a quite large LONS background. This together with the large ZA requires to take either dedicated OFF data or to take data in the wobble mode. Since the LONS level is in any case very large moon observations are considered in addition to the normal observations.
 
 
 \section{Requested Observation Time}
 
-Based on the above estimations a 5 $\sigma$ excess is expected to be observed in about 2 hours assuming the HESS flux. To acquire a data set which is comparable in size to those of the other experiments at least 20 hours of good ON data and 20 hours of good dedicated OFF data are needed. 
+Based on the above estimates a 5 $\sigma$ excess is expected to be observed in about 2 hours. To acquire a data set which is comparable in size to those of the other experiments at least 40 hours of observation time are requested. These 40 hours may be either split into 20 hours ON and 20 hours OFF data taking or be devoted exclusively to data taking in the wobble mode. It is still being uinvestigated which of the observation modes is to be prefered.

-To extend the available observation time we propose to take moon ON and OFF data in addition. Nevertheless, the proposed maximum ZA of 60 deg should not be exceeded during moon observations.
