Extended Data Fig. 7: Transmission spectroscopy metric, emission spectroscopy metric and simulated spectra for JWST.
a,c Transit and emission spectroscopic metrics for TOI-1853 b (golden hexagon marker) in comparison with the population of transiting exoplanets (grey markers) and those selected for JWST cycles 1 and 2 observations (purple and green markers). TOI-1853 b has a transmission spectroscopy metric of 2.6 and an emission spectroscopy metric of 10.9. b, Synthetic transmission spectra for an H2-dominated atmosphere (solid orange line) and an H2O-dominated atmosphere (solid blue line). The markers with 1σ error bars show simulated JWST observations for selected detectors when combining three transits each. d, Same as b but for synthetic emission spectra.
