Posterior probability distribution of our grid of models with respect to each of their parameter pairs as well as the marginalised distribution for each parameter for HD 189733 b (red) and GJ 3470 b (blue). The marginalised uncertainties are given as 16 to 84% quantiles. In the density maps, 1- and 2-σ are given as 1-e^−0.5 ~0.393 and 1-e^−2.0 ~0.865, respectively,as are common for multivariate MCMC results.
