Abstract

We present here the set of corrections that will be applied to the raw data of the CoRoT mission. The aim is to correct the data for instrumental and environmental perturbations as well as to optimize the duty-cycle, in order to reach the expected performances of the mission. The main corrections are : the correction of the electromagnetic interferences, suppression of outliers, the background correction, the jitter correction and the correction of the integration time variations. We focus here on these corrections and emphasize their efficiency.
