Same as Figure 6, but for the SO₂-bearing atmospheres of T-1 d. Solid, dashed, and dotted lines indicate that 100 ppm, 0.1%, or 1% SO₂, respectively, was added to the bottom layer of the atmosphere. When including SO₂, the H₂O–CO₂ outgassed, O₂-dominated, or mixed O₂–H₂O–CO₂ atmospheres were found to be stable, so those rows are not present in this figure. When including trace SO₂, the fit to available transmission data (C. Piaulet-Ghorayeb et al. 2025) is changed negligibly, with all atmospheres providing fits to <1σ.
