Caption: Figure 5.

Atmospheric constraints on the HR 8799 planets. On the left are 1D and 2D marginalized posteriors of T_eff and ﹩\mathrm{log}(g)﹩ for HR 8799 c (red), d (green), and e (yellow). The 2D plot shows the 68% (solid) and 95% (dotted–dashed) credible region for each planet. A strong positive correlation between T_eff and ﹩\mathrm{log}(g)﹩ is observed. Black points and dotted lines correspond to representative models, which are plotted on the right.
