Posterior probability distributions of the model parameters for a simulated observation of the no-cloud atmospheric configuration at S∕N = 10. The planetary radius is considered unconstrained. Green lines mark the true values of the model parameters (see Table 2) for this observation. Two-dimensional subplots show the correlations between pairs of parameters. Contour lines correspond to the 0.5, 1, 1.5, and 2 σ levels. The median of each parameter’s distribution is shown on top of their 1D probability histogram. Upper and lower errors correspond to the 84 and 16% quantiles.
