Best-fit models for the WASP-17b NIRISS SOSS observation obtained using uniform (orange line) and informative (blue line) priors compared to the best-fit model by Louie et al. (2025) (green line). The residuals show that our two models are consistent, differing only in the 2.25–2.5 µm wavelength range. As for WASP-39b, our atmospheric model cannot describe all spectra features, such as the strong H₂O features at ∼1.4, ∼1.8, and above 2.5 µm.
