Best-fit model from the fiducial retrieval to the observed spectrum at 0° phase, whose uncertainties are smaller than the displayed line width. This model assumed a fixed mass and radius of 10.381 M_Jup and 0.9329 R_Jup respectively. Also shown for visual reference are the log opacities at the 1 bar level of the primary absorbers in each wavelength range. The CH₄ abundance was allowed to vary as a function of altitude. The reduced χ² of the t s T. However, the model clearly matches the key absorption features of H₂O, CH₄, CO, and CO₂, as well as additional species such as H₂S and NH₃.
