Köln, RIU-Planetary Research, Cologne Detection Pipeline Trapez fitting, ranking, parameter determination ExoTrans PHALET (Talk by Grziwa) ExoTrans DEBIL (Check for binary star) VETO

Deep binary from original lightcurve Lightcurve filtered and first transit signal removed Second signal found Test on CoRoT lightcurves Orbit period: days Signal depth: ~10% Orbit period: days Signal depth ~ 0.8 %

Conclusion and Outlook The multi transit pipepline is up and running Finds multiple transit signals in a single lightcurve Multiple planet system Planet in a stellar binary Implementation fast and reliable → valuable tool for future mission PLATO
