Retrieved TPs for leading hemisphere datasets: M22-L (top row) and J21-L (bottom row). Columns show the 3T, 2T, and 1T parameterizations (left to right). The black curve is the best-fit TP; the gray band marks the 1σ credible interval. The legend for each profile provides the best-fit SO₂ column density, fractional coverage, wind dispersion parameters, and, when applicable, the transition pressure (with 1σ errors). Left axes give pressure; right axes show the corresponding altitude. The dashed horizontal black line indicates the modeled surface pressure, quoted with uncertainties calculated from the upper and lower bounds of the SO₂ column density.
