Posterior distributions from the retrieval of the atmospheric and orbital parameters. The dashed lines indicate the mean value and the 16th and 84th percentile. The included parameters consists of the three parameters defining the T–p profile (T_irr, κ_IR, γ), the orbital semi-amplitude of the planet (K_p), the offset from the expected planet rest frame (v_offset), a scaling factor to the uncertainties (β), the equatorial rotation velocity (v_eq) and two parameters determining the equilibrium chemistry (C/O ratio and metallicity).
