Notes. The estimates correspond to the posterior median (P50) with 1σ uncertainty estimate based on the 16th and 84th posterior percentiles (P16 and P84, respectively) for symmetric, approximately normal posteriors. For asymmetric, unimodal posteriors, the estimates are . (a) The semi-major axis and planet candidate radius are based on the scaled semi-major axis and true radius ratio samples, and the stellar radius estimate shown in Table 1. (b) The equilibrium temperature of the planet candidate is calculated using the stellar TEff estimate, scaled semi-major axis distribution, heat redistribution factor distributed uniformly between 0.25 and 0.5, and planetary albedo distributed uniformly between 0 and 0.4.
