Posterior joint distributions of parameters for atmospheric retrieval. The contours indicate 39.3%, 86.5%, 98.9% (1- to 3-σ) credible intervals. The diagonal panels show the marginal distributions of corresponding parameters, in which the vertical dashed lines indicate the medians and 68.2% credible intervals. The specific values of posteriors are listed in Table 4. This figure is plotted utilizing the Python package corner (Foreman-Mackey 2016).
