Abstract
COROT is a mission of the CNES space agency, to be launched in 2005 in a Polar orbit. Its main goals are the search of stellar oscillation and the exoplanet detection. Five star fields chosen close to the galactic plane and in the opposite direction will be observed with an high photometric stability. Four 2048x2048 CCD detectors cover two detection areas one for asteroseismology and the other for exoplanets detection. To avoid the saturation risk the seismology area is just in front of focal plane; in the exoplanet area a low power prism disperses the images to get color information about each observed star. This paper presents the procedure used to deduce the polychromatic PSFs for both the seismology and the exoplanets detection areas depending on position and star color indexes. The use of standard optical packages, the expected inaccuracies and performances are discussed.
