Histogram of the visual magnitudes of the stars observed by CoRoT in eleven exoplanet fields. The full line represents all stars, the dashed line only those that were observed in the CHR-mode. The thick (red) points indicate the brightness of the planet-host stars found in the “galactic center” (C-planets) and “anti-center eyes” (A-planets) of CoRoT. The asterisks shows the brightness of the planet-hosting stars observed in the MONO-mode.
