Abstract:
We introduce the CoRoT Detrend Algorithm (CDA) for detrending CoRoT
stellar light curves. CDA has the capability to remove random jumps
and systematic trends encountered in typical CoRoT data in a fully
automatic fashion. Since huge jumps in flux can destroy the
information content of a light curve, such an algorithm is essential.
From a study of 1030 light curves in the CoRoT IRa01 field we
developed three simple assumptions CDA is based upon. In this paper we
describe analytically the algorithm and we provide some examples of
how it works. We demonstrate its functionality of the algorithm in the
cases of CoRoT0102702789, CoRoT0102874481, CoRoT0102741994 and
CoRoT0102729260. Using CDA in the specific case of CoRoT0102729260 we
detect a candidate exoplanet around the host star of spectral type G5,
which remains undetected in the raw light curve; the estimated
planetary parameters are Rp=6.27RE and P=1.6986days.
Description:
Requirements : gfortran (or g77, ifort) compiler
Input Files : The input files sould be raw CoRoT txt files
(http://idoc-corot.ias.u-psud.fr/index.jsp) with names CoRoT*.txt
Run the cda by typing
C>: ./cda.csh
(code and data sould be in the same directory)
Output files : CDA creates one ascii output file with name -
CoRoT*.R.cor for R filter
