Caption: Figure 10.
C/O vs. volatile abundance (left), C/O vs. planet mass and equilibrium temperature (upper row), and volatile abundance vs. planet mass and equilibrium temperature (lower row). The free retrieval values are shown in black and the equilibrium retrievals in blue. The equilibrium values have been slightly offset in mass and temperature for clarity. None of these parameters appear to be significantly correlated. Compared to the free retrievals, the equilibrium retrievals tend to prefer slightly lower C/O and higher volatile abundances, leading to weak clustering in the low-C/O, high-volatile region of the left plot, which is not seen in the free retrieval case. The uncertainties in these parameters are too large to definitively establish or reject any correlations between these parameters.
