Phase-folded transit light curve of Kepler-77. Short- and long-cadence Kepler data are shown in the left and right panel, respectively, binned at ~1.7 min. The best-fitting model is overplotted with a solid grey line. The dashed vertical lines mark the planet’s true first and fourth contact. The apparent transit duration is longer for the LC data than for the SC data, owing to the low time resolution.
