| Abstract: |
In the CoRoT exoplanet field of view, photometric measurements are obtained by
aperture integration using a generic collection of masks. The total flux held
within the photometric mask may be split in two parts, the target flux itself
and the flux due to the nearest neighbours considered as contaminants. So far
ExoDat (http://cesam.oamp.fr/exodat) gives a rough estimate of the contamination
rate for all potential exoplanet targets (level-0) based on generic PSF shapes
built before CoRoT launch. Here, we present the updated estimate of the
contamination rate (level-1) with its associated error. This estimate is done
for each target observed by CoRoT in the exoplanet channel using a new catalog of
PSF built from the first available flight images and taking into account the
line of sight of the satellite (i.e. the satellite orientation). |
