1. EXODAT : a Data Base for the CoRoT/ Exoplanet channel Laboratoire d’Astrophysique de Marseille M. Deleuil J.C. Meunier C. Moutou A. Llebaria L. Jorda P. Barge & H. Deeg - Institute Astrofisica Canaria

2. Why this DB?  Ground-based observations :  Archive the data  Perform the spectral classification  Validate algorithms: - allocation of the best photometric mask - estimate the contamination for each potential target  Prepare the scientific analysis  Validate the data provided to CoRotSky for the Exoplanet channel

4. Tools in ExoDat The classification software; Selections by combination of : positions (α,δ); magnitudes, colors, spectral type, luminosity class. Visualisation facilities:  diagrams ( ,  ), color – magnitude,..  histograms

5. ExoDat Status Under development ; Open to ExoTeam on request; Link with CoRoTSky.
