1 1 COROT: Scientific comity Sept 15 2006 Calibrations during the commissioning and before the first run. Calibrations cover closed Calibrations cover open Content

2 2 COROT: Scientific comity Sept 15 2006 Cover closed. Goals. Effect of the temperature on: The dark current. The electronic offset

3 3 COROT: Scientific comity Sept 15 2006 Gain measurement of the 8 electronic chains. µ = σ 2 (Poisson) gain. µ gain 2. σ 2 ADC: gain = σ 2 / µ CCD: Precision ~1% Cover closed.

4 4 COROT: Scientific comity Sept 15 2006 Bright pixels: Position and intensity Function of the integrated radiations flux Cover closed.

5 5 COROT: Scientific comity Sept 15 2006 Calibration of the cross-talk between: Exoplanet Asteroseimology CCD Asteroseimology CCD A1 A2 PF channel AS channel Cover closed.

6 6 COROT: Scientific comity Sept 15 2006 South Atlantic Anomaly Verify that the shielding eliminate the electrons of the polar belts. Protons flux measurement. Validate the SAA limits. Statistics on: Intensity of the impacts. Number of pixels perturbed. Brightest pixel in an impact. Statistic on MOST data Cover closed.

7 7 COROT: Scientific comity Sept 15 2006 Cover opened Rough calibrations of the baffle efficiency. may imply a modification of the runs planning.

8 8 COROT: Scientific comity Sept 15 2006 PSF reconstruction on the seismology channel. Resolution of 1/3 pixel. Cannot be done in the same way on the PF channel acquired data projected image spline interpolation Image with jitter Designed to optimize a PSF fitting on imagettes Reconstructed Image Cover opened
