Our retrieved and the inferred elemental abundance ratios normalized to the solar value of M. Asplund et al. (2021). The P/H ratio is a 3σ upper limit. The blue shaded regions denote the 1σ, 2σ, and 3σ interval range of the retrieved C/H ratio. After correcting for nondetected molecules and atmospheric processes as described in Section 4.4, the inferred C/H, N/H, O/H, S/H, and C/S values agree to each other within uncertainties. The retrieved and inferred C/O ratios are both above the solar value even after accounting for oxygen sequestration during silicate cloud formation.
