Abstract

The Fermi Gamma-ray Space Telescope is programmed to have a proper motion during its flight: if a gamma-ray burst occures, the satellite changes its orientation toward the burst. This rapid rotation has a contribution to the measured data, therefore, the background of a lightcurve varies in time. In order to get the statistical parameters of a burst, we need to separate the data from the background. In this paper, we present a new backgroundfiltering method based on the motion and orientation of the satellite, considering the celestial position of the burst, the Sun and the Earth as well. We show that our method is effective to compute the statistical parameters and it is appropriate for the Fermi's data set.
