Marginal posterior distributions of the C/O ratio and metallicity ([(C+O)/H]) derived from molecular abundances for all JWST instrument combinations. An additional retrieval of all JWST instruments using the NIRSpec TEATRO instead of the standard CASCADe reduction is also shown (labeled TEATRO). The interval markers follow the convention introduced in Fig. 4. Solar (⊙; Asplund et al. 2021) and stellar (★; Biazzo et al. 2022) values are indicated on the top axis. The gray shading marks the uncertainty in the stellar values.
