Left panel: the best-fit PICASO retrieval temperature–pressure (T-P) profile is plotted as a solid blue line with the temperature–pressure knots indicated in solid blue circles. The light-blue shaded region indicates the 3σ confidence interval of the retrieved T-P profiles. The tightly constrained T-P profiles in the 1–10 bar range match with the peak of the 3–5 μm contribution function plotted in the right panel. The retrieved T-P profile based on MIRI-LRS 5–11.7 μm spectrum in M. Voyer et al. (2025) is plotted in solid purple along with the 3σ uncertainty plotted as light-purple shaded region. The condensation curves of H₂O, Na₂S, and KCl at solar metallicity are plotted with blue, orange, and green dashed lines, respectively. For reference, the solid black line shows the T-P profile of the best-fit Elf Owl grid model ([M/H] = −1, C/O = 1.5, log(g) = 3.23, log(K_zz) = 7, T_eff= 350 K). Right panel: the contribution function map of the best-fit PICASO retrieval results shows that most of the 3–5 μm flux is emitted from 0.1–10 bar region.
