Left: marginal posterior distributions (histograms) when the WFC3 and O1 data are included. The shaded red areas denotethe 68% confidence intervals of the respective distributions. The light green dashed vertical lines denote the retrieved best-fit parameter values. Strong non-linear correlations seen in the right panel of this figure produce that some of the best-fit parameter values fall outside of the red credible regions, and cause gaps in the water confidence interval, reflecting a bi-modal posterior distribution. Right: pair-wise correlation plots with posterior densities.
