The requirements are presented for the measurement of the main beam, the intermediate zone, the spillover zone, and the straylight region, respectively. These regions (in position and shape) have been identified for each considered beam pattern, in the S/C coordinate system. The accuracy level to be reached in the measurement of each region is reported.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICA
