Comparison of extracted exoplanet spectra to GCM results. All measured spectra and models are normalised by the average of the spectrum across the bandpass in order to allow a comparison to our relative spectra. Top: data for the eclipse (in green) as well as the dayside spectrum extracted by Stevenson et al. (2014, in dashed black). Bottom: extracted quadrature spectrum (in orange). For both panels the models are shown for solar composition (red), no-dissociation (blue), no H- (purple), no molecular opacity (grey), and factor-two higher optical opacity (pink).
