Extended Data Fig. 8: Retrieved pressure-dependent H2O abundances.
From: Diurnal variations in the stratosphere of the ultrahot giant exoplanet WASP-121b
Same format as Extended Data Fig. 5, but showing posterior distributions for the retrieved H2O abundances. ATMO credible ranges are much narrower than those of NEMESIS, due to the metallicity being fixed for the ATMO retrievals whereas the H2O abundance was unconstrained for the NEMESIS retrievals.
