Notes. The same priors were used for each white light fit, with the exception of the transit midpoint, which was adjusted for the observation time. The GP parameters for the lengthscale (log ρ) and amplitude (log σ) of the correlated noise and the jitter parameter (also in log-scale) have uniform priors. In the transit midpoint prior, t is used to indicate the date-dependant (visually) estimated value used as a prior. The second part of the table contains the physical properties of the system as derived from the fitted parameters.
