Abstract

This is an overview of the processing of the dispersed images for the Blue and Red Photometers in the Gaia Satellite. The data are corrected for CCD related effects in the pre-processing, where also the sky background and the flux by neighbours are removed; the data are then internally calibrated to the same “mean instrument” and externally calibrated to obtain spectrum and flux in physical units, which will be stored in the final catalogue.
