Comparison of the multi-molecule, free-chemistry retrieval models to low-resolution data. Top panel: predicted relative transit depth change from the free chemistry models retrieved from CRIRES⁺ data (green). The model predictions are plotted in high-resolution in the wavelength region overlapping with the CRIRES⁺ remeasurements indicated by the grey shaded areas and in low-resolution for the rest of the wavelength range. Space-based measurements from HST (blue) and JWST (orange) are also shown. The 1σ and 1.5σ uncertainties of the model are indicated as darker and lighter green shaded areas, respectively. The HST-WFC3 and JWST NIRSpec G359H measurements were taken from the online data provided by Schlawin et al. (2024) containing the HST data adapted from Kreidberg et al. (2014). Bottom panel: the contributions to the model by the opacities of the individual molecules are shown including the 1σ and 1.5σ uncertainties. H₂S and NH₃ are not shown as they do not contribute to the opacities of the global model in any of the shown wavelength regions based on the retrieved VMRs.
