摘要

COROT is a mission of the CNES space agency, to be launched in 2005 in a near Polar orbit. It is devoted to star seismology and to exoplanetary transit search. Five star fields chosen close to the galactic plane will be observed during the mission with a high photometric accuracy (relative). Each observation run will last 150 days monitoring continuously more than 6000 stars. This paper presents a new method designed to perform optimal aperture photometry on board in high density fields. We describe the way the photometric windows or patterns are defined and centered on the CCD around each target star, with the expected performances. Each pattern depends on the specific 2D profile of the point spread function (PSF) but also on the pointing jitter and on the tiny deformations of the telescopes. These patterns will be stored on board in order to define for each target star the optimal pattern which will produce the integrated flux to be measured. This method allows a significant increase of the sampling rate to approximately one measure per star each 8 mn).
