The spectral contributions from H₂O, CO, CO₂, SO₂, and H₂S to the best-fit spectrum obtained from the retrieval on JWST observations reduced by the Tiberius pipeline combined with HST/WFC3 data. Also shown is the resulting spectrum from all molecular spectral contributions, corresponding to the aerosol-free model shown in Figure 1. Spectral contributions from MgSiO₃ aerosols as shown in Figure 1 are not included here, for visual clarity.
