VizieR Online Data Catalog: CoRoT transit catalogue (Deleuil+, 2018)

Abstract : We provide the full catalogue of all the transit-like events identified in the CoRoT light curves during the mission lifetime by the CoRoT collaboration. It includes planet candidates that were identified after the release of each run, their status once follow-up observations were completed, and also binaries. The later were separated in two groups: detached eclipsing binaries and contact binaries. All these events, whose detection was performed by different teams in a first stage, have been re-analysed with a unified procedure and using the same softwares so that to derive, in a homogeneous and consistent way, the complete set of transit parameters, using fixed limb-darkening coefficients because of the uncertainties on the spectral classification. In addition to this modelling, we also carried out a vetting process of both candidates and binaries. It is based on a simple binary flag system over basic tests: detection significance, presence of a secondary, odd or even depth differences, colour dependence, Vshape transit, and duration of the transit. Among the 4123 transitlike signals that were analysed, it allowed us to identify periodic signals that are instrumental false positives and false detections. In total, the presented catalogue comes up with 594 events initially flagged as planet candidates which include published planets and brown dwarfs, 1653 EBs, 616 contact binaries, and 824 false alarms.
