Atmospheric properties of the three different modelled regions of the planet. Panel a: sketch of the three different regions retrieved for the planet atmosphere. Panel b: probability distributions of the temperature and cloud top pressure retrieved for the three regions. The isolines indicate the 1 and 2σ levels of a 2D distribution, i.e. encompassing 39.3 and 86.0% of all posterior samples, respectively. The blueshifted terminator region is indicated in blue, the redshifted terminator region is indicated in red, and the polar region is indicated in grey. Panel c: histograms of the temperature distributions. Panel d: histograms of the cloud top pressure distributions. The mean values of the distributions are indicated with a dashed line. The respective values are quoted in the plot, together with the 1σ uncertainties of a 1D distribution, i.e. determined as the values that encompass 68.0% of the distribution.
