Stacked transits of KOI3184.03 (top), Kepler-1972 b (middle), and Kepler-1972 c (bottom). The left panel results from the stacking along the Keplerian ephemeride, which is the left solution in Table 2. The right panel shows the result of stacking along the Keplerian ephemeride for the inner planet, and the n-body solution for Kepler-1972 b and c, which is the solution on the right-hand side of Table 2.
