Detrended Kepler light curve of KOI-0340. In all panels small gray circles represent the Kepler data and the red filled circles is a binning of the whole data with a bin size of 0.005 in phase. Upper panel shows a zoom to the primary transit and the fitted primary eclipse with a solid black line (see Sect. 4). Middle panel shows the detected secondary eclipse and the fit obtained in Sect. 4 as a solid black line. Lower panel shows the residuals of the fit, with a standard deviation of 173 ppm in the original dataset and 36 ppm in the binned light curve.
