  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.
