Abstract
Ground calibrations have been completed in 1998 on the MOS-CCD focal planes of the European Photon Imaging Cameras (EPIC) of the X-ray Multi-Mirror (XMM) mission. The cameras have been calibrated as a whole, including the digital treatment performed in the EPIC MOS Controller (EMCR), where events are selected according to a library of preset patterns and some of their parameters saved for ground off line reconstruction. This paper presents results of the calibration data analysis about the X-ray event selection as a function of the EMCR configuration parameters and the X-ray event energy reconstruction on the pattern basis. Spectral performances of the cameras as well as the background rejection are presented as a function of the reconstruction scheme adopted.
