 At La Palma, the GC culminates at about 58 deg zenith angle (ZA). It can be

 Comparing this to the expected MAGIC sensitivity from MC simulations, this 
 could result in a 5 $\sigma$ detection in about $1.8\pm0.5$ hours.

-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 region has a quite high and non-uniform level of background light from the night sky. This together with the large ZA requires to take either dedicated OFF data or to take data in the wobble mode (see Section \ref{section:skydirections}).

 \section{Requested Observation Time}
 
-Based on the above estimates, a 5$\sigma$ excess is expected to be observed in about 2 hours, under optimal conditions. 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. At present, the prefered mode is the wobble mode. However, a final decision has not yet been taken.

 As pointed out in Section \ref{section:feasibility}, all data should be taken at the
 smallest possible zenith angles between culmination at about 58 deg and 60
-deg. This limits the data taking interval to about 1 hour per night between
-April and August.
