Volume mixing ratios (VMRs) in 2 M0355 (top) and 2 M1425 (bottom) of the main atmospheric species retrieved using free versus equilibrium chemistry. For clarity, the free chemistry abundances are only shown as markers with errorbars, while the equilibrium chemistry abundances, which vary throughout the atmosphere, are shown as solid lines. The errorbars and shaded envelopes show the retrieved 95% confidence interval. The integrated emission contribution function (dotted: free, solid: equilibrium) is shown on the pressure axis for reference.
