Same as Figure 6, but for the SO₂-bearing atmospheres of T-1 c. 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 no mixed CO₂–CO, and H₂O–CO₂ outgassed, O₂-dominated atmospheres were found to be stable, so those rows are not present in this figure. When including trace SO₂, all types of H₂O outgassed atmospheres may provide good (<1σ) fits to all available emission data.
