Determination of the contamination rate for CoRoT targets

Benjamin Gardes (Laboratoire d'Astrophysique de Marseille), Pierre-Yves Chabaud (Laboratoire d'Astrophysique de Marseille)


In the CoRoT field of view, photometric measurements are obtained by aperture integration using a generic collection of masks.
The information held within the photometric masks may be splited in two parts,
the target flux itself and the flux due to the nearest neighbours considered as contaminants.
Therefore, we describe the procedure and the criteria used to compute the level of contamination based on the global simulation of the field of view for each run.
Then, we introduce the method to estimate the associated contamination error.
Finally, first results are given from CoRoT-1 to CoRoT-24 planetary candidates.
