Posterior distributions of a selection of parameters for the Luhman 16AB one-column retrievals. For both objects, we find a strong correlation between the surface gravity, log g, and the abundances. However, the retrieved surface gravities do not deviate from the imposed Gaussian priors, which implies that the constrained abundances are accurate. The radial velocity, v_rad, shows no correlation and could therefore help constrain the Luhman 16AB orbits further.
