Top panel: evolution of the fitted impact parameter over time. Each point corresponds to a separate short-cadence Kepler quarter. The red line is a least-squares fit from which we report the rate of change of b. The horizontal error bars show the time span of each quarter. Second panel: fitted values of the sky-projected spin–orbit misalignment λ for all quarters. Third panel: fitted values of the stellar inclination φ for all quarters. Bottom panel: evolution of the fitted time of mid-transit over time. The red line shows a least-squares fit from which we find a very small rate of change.
