Notes. The median values of the posterior distributions of the model parameters are reported, along with lower and upper uncertainties. These uncertainties correspond to the 15.9th and 84.1th percentiles of the posterior distributions for each parameter. The last column reports the prior bounds that were used for all parameters; 𝒩(μ, σ) is a normal distribution centred in μ and with variance σ2, and 𝒰(a, b) is a uniform distribution in the (a, b) interval. ( * )Value from Shahbaz et al. (2022). ( † )Value from Bogdanov et al. (2018).
