Fig. 3: Data comparison against a 1D-RCPE model and residuals for the JWST spectrum of WASP-39 b.

From: A benchmark JWST near-infrared spectrum for the exoplanet WASP-39 b

Fig. 3

a,b, JWST transmission spectrum of WASP-39 b with 1σ uncertainties (black hexagons), split at ~2.0 µm for clarity alongside archival data (grey hexagons). a, λ < 2.0 μm. b, λ > 2.0 μm. For PRISM, the data are at the native spectral resolution. Data in the saturated region are excluded. For the other modes, the data are at R = 100. Results from the model with ×10 solar metallicity and C/O = 0.35 are displayed in purple. c, Residuals of the data for each mode relative to the best-fitting model in addition to their 1σ uncertainties (shaded regions). d, Probability density of the residuals for each mode relative to the best-fitting model.
