    266 Based on the above estimations a 5 $\sigma$ excess could be expected to be observed in about 2 hours assuming the HESS flux. To aquire a comparable data set to the other experiments at least 20 hours of good ON data and 20 hours of good dedicacted OFF data are needed.

    267270
    268271To get the lowest possible threshold all data shall be taken under 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. In order to have the most appropriate OFF data we propose to take OFF data each night directly before or after the ON observations under the same condition, i.e. ZA and azimuth.
    269272
    270 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 monn observations.
    271 
    272 In order to take part in exploring the exciting physics of the Galactic Center we propose to start taking data as soon as possible beginning in April. This way first results may be presented in the summer conferences 2005.

    279282Conventional acceleration mechanisms are due to ... The galactic center is expected to be the brightest source of VHE gammas  from particle dark matter annihilation. Although the observed gamma radiation is most probably not due to dark matter annihilation, it is interesting to investigate and characterize the observed gamma radiation as it is not excluded that a part of the flux is due to dark matter annihilation.
    280283
    281 The MAGIC data could help to determine the nature of the source and to solve the flux discrepancies between the measurements by the other experiments. Due to the large Zenith angle MAGIC will have a large energy threshold but also a large collection area and good statistics for the highest energies. The observation results can also be used to inter-calibrate the different IACTs.
