Extended Data Fig. 6: Gaussian versus flat-line fits to the residual transmission spectrum for CO2, H2O, SO2 and the 4.56-μm feature.

From: Early Release Science of the exoplanet WASP-39b with JWST NIRSpec G395H

Extended Data Fig. 6

Shown after all other absorption from the best-fit model is subtracted from the data. Each of the Gaussian fits has a higher Bayesian evidence than the flat-line fits, indicating a detection, although to varying degrees of significance.
