Notes. (a)The uncertainties are given as the 16th and 84th percentiles of the posterior distributions. For some of the parameters, we provide the 95th percentile in parenthesis. (b)In place of a/R★, we used the stellar density ρ* as a free parameter with Gaussian prior 𝒩(1.376,0.078) ρ⊙, from which we derived the ap/R★ ratios at each step of the MC sampling.(c) A systematic error of at least 1 % of the best-fit radius should be added, to take into account effects due to stellar activity (Sect. 5).
