Notes. The upper part of the table lists the fitted parameters with their corresponding prior probabilities. Uniform prior probabilities are represented with 
, where xmin and xmax are the minimum and maximum allowed values, respectively. Normal (Gaussian) prior probabilities are written as
, where μ and σ are the mean and standard deviation of the normal distribution, respectively. The lower part of the table shows the values of parameters derived from the sampled parameter space. (†)The values of Ag and Fday both define the eclipse depth and are thus degenerate. This induces a strong linear correlation between the two parameters and the values reported in the table are not representative of any convergence. The eclipse depth obtained from Ag and Fday is a well-defined quantity and should be the one to refer to. (‡)The hotspot offset is unconstrained for small values of Fday where Ag solely contributes to the phase curve amplitude. The value of ϕtherm reported in the table is computed for values of Ag < 0.05 to ensure reliable estimates of uncertainties.
