Notes. We only list the parameters that are relevant to follow-up analyses. However, the joint analysis involves 75 free parameters. The priors of all these additional parameters were taken as non informative. We assumed R⊙ = 695 508 km, M⊙ = 1.98842 × 1030 kg, R⊕ = 6378 km, M⊕ = 5.9736 × 1024 kg, and 1 AU = 149 597 870 km. Temperature Teq was derived assuming a null albedo, and Tlock assuming tidally synchronized rotation. Symbol † indicates that the 99% confidence interval is also given into parentheses. Notation: N$\[\boldsymbol{\mathcal{N}}\]$(μ, σ) refers to a Gaussian distribution with mean μ and standard deviation σ; T$\[\boldsymbol{\mathcal{T}}\]$N$\[\boldsymbol{\mathcal{N}}\]$(μ, σ) to a truncated-normal distribution; A$\[\boldsymbol{\mathcal{A}}\]$N$\[\boldsymbol{\mathcal{N}}\]$(μ, σ−, σ+) to an asymmetric normal distribution with asymmetric width σ−/σ+; U$\[\boldsymbol{\mathcal{U}}\]$(a, b) to a uniform distribution between [a, b]; and Sine(a, b) to a sinusoidal distribution between a and b.
