Median values of the carbon-to-oxygen ratio (C/O) inferred from both our nested sampling and random forest retrievals. Only retrievals performed on NIRCam (top panel) and NIRSpec PRISM (bottom panel) spectra are considered (see text for more details). Only models with the logarithm of the Bayes factor being less than unity (relative to the model with the highest Bayesian evidence) are shown. The three horizontal blue lines are C/O ratios taken from Ahrer et al. (2023b) for NIRCam, while the four horizontal yellow lines are those taken from Rustamkulov et al. (2023) for NIRSpec PRISM. The dashed grey line indicates the solar value of 0.55 (Asplund et al. 2009), while the solid grey line represents the stellar value of 0.46 ± 0.09 (Polanski et al. 2022).
