Description
This paper presents an analysis that searched for systematic effects
within the CoRoT exoplanet field light curves. The analysis identified a
systematic effect that modified the zero point of most CoRoT exposures
as a function of stellar magnitude. We could find this effect only after
preparing a set of learning light curves that were relatively free of
stellar and instrumental noise. Correcting for this effect, rejecting
outliers that appear in almost every exposure, and applying SysRem,
reduced the stellar RMS by about 20%, without attenuating transit
signals.
The CoRoT space mission, launched on December 27th 2006, has been
developed and is operated by CNES, with the contribution of Austria,
Belgium, Brazil, ESA, Germany, and Spain. CoRoT data become publicly
available one year after release to the Co-Is of the mission from the
CoRoT archive: http://idoc-corot.ias.u-psud.fr/.

The principal objectives of this project are: 1) to study the structure and dynamics of the solar interior, 2) to extend this study to other stars, 3) to search for extrasolar planets using photometric methods (primarily by transits of their host stars) and their characterization (using radial velocity information) and 4) the study of the planetary
