Spectral energy distribution of WASP-24b relative to that of its host star. The blue circles with error bars are our best-fitting occultation depths. The light green line is a model-atmosphere spectrum, based on a model which assumes solar abundances in thermochemical equilibrium and lacks a temperature inversion, and the dark red line is a model with a temperature inversion. The band-integrated model fluxes are indicated with circles of the corresponding colours. The dashed black line shows a planetary black body model with a temperature of 1900 K. Inset: temperature-pressure profiles for our models.
