Detrended Kepler light curve of KOI-3725 and phase-folded by using the new calculated period (i.e., P_orb = 3.1409940 ± 0.0000008 days), twice the one published by the Kepler team. The unequal depth of odd/even transits is clear evidence of the binary nature of this object. Upper panel shows the entire phase of the system. Lower panel shows a zoom to the odd and even transits (in different colors and symbols). The primary transit has been shifted to φ = 0.5 for comparison purposes. The transit model is shown as solid gray lines.
