Posterior distributions for the C/O ratio and metallicity of the planet atmosphere. Bottom left: Posterior distributions from the retrievals for the C/O ratio and metallicity [Fe/H] of the planet (in blue). The isolines encompass 1, 2, and 3σ. Solar values are indicated by a red dotted line and the values obtained for the host star (Boucher et al. (2023) are depicted by an orange dashed line. The median values of the planet value distributions are indicated with a dashed blue line in the histograms for the C/O ratio (top left) and the metallicity [Fe/H] (bottom right) and quoted above the panels with the respective histograms together with the 1σ uncertainties. The dashed blue line for the median values falls nearly on top of the red dotted lines indicating the solar values.
