r6852 r6853 61 61 62 62 At La Palma, the GC culminates at about 58 deg zenith angle (ZA). It can be 63 observed with MAGIC at up to 60 deg ZA, between 64 April and late August, yielding a total of 150 hours without moon per year. 65 The expected integral flux above 700 GeV derived from 66 the HESS data is $(3.2 \pm 1.0)\cdot 10^{-12}\mathrm{cm}^{-2}\mathrm{s}^{-1}$. 63 observed with MAGIC at up to 60 deg ZA, between April and late August, yielding a total of 150 hours without moon per year. 64 The expected integral flux above 700 GeV derived from the HESS data is $(3.2 \pm 1.0)\cdot 10^{-12}\mathrm{cm}^{-2}\mathrm{s}^{-1}$. 67 65 Comparing this to the expected MAGIC sensitivity from MC simulations, this 68 66 could result in a 5 $\sigma$ detection in about $1.8\pm0.5$ hours. … … 85 83 In order to collect a data sample comparable in size to those of the other 86 84 experiments and to be able to measure the energy spectrum, 40 hours of 87 observation time are requested. This 40 hours will be split into 20 hours ON 88 and 20 hours dedicated OFF data or they will be devoted to observations in 89 the wobble mode. In addition, 60 hours of observation during moonshine are 90 applied for. 85 86 observation time are requested. The observations should be preferably conducted in the wobble mode or the 40 hours split into 20 hours ON and 20 hours dedicated OFF data taking. For the final decision dedicated studies are being carried out. In addition, 60 hours of observation during moonshine are applied for. 87 91 88 \end{abstract} 92 89 … … 440 437 441 438 442 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}). 439 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 moon-less 150 hours. Moreover there are more than 100 hours in the same ZA range with moon light. 440 441 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 observations in the wobble mode (see Section \ref{section:skydirections}) or to take dedicated OFF data. 442 443 443 %Since the LONS level is in any case very large moon observations are considered in addition to the normal observations. 444 444 … … 515 515 \section{Requested Observation Time} 516 516 517 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.517 Based on the above estimates, a 5$\sigma$ excess is expected to be observed in about 2 hours, under optimal conditions.

This limits the data taking interval to about 1 hour per night between 522 April and August. 523 524 525 To increase statistics at high energies we propose to take additional data during moonshine. Also in this case, the maximum ZA of 60 deg should not be exceeded. 521 deg starting in April. To increase statistics we propose to take data during moonshine in addition. Also in this case, the maximum ZA of 60 deg should not be exceeded. 522 523 %This limits the data taking interval to about 1 hour per night between 524 %April and August. 525 526 526 527 527 528 In order to take part in exploring the exciting physics of the GC
