Comparison between retrieved best-fit spectrum and models without an upper atmosphere inversion to determine the contribution from the hot spot, similar to Fig. B.1. Top: comparison of each of the spectra, with the inset panel showing the differences in the temperature profile. Centre: ratio between the two retrieved spectra with the maximum (105°) and minimum (195°) inversion strengths, as well as a model without an inversion. Bottom: comparison of the best-fit model at 105° and the non-inverted model to the observed spectrum. The data are shown with 10σ uncertainties for visibility.
