Geometric albedo as function of planet day-side brightness temperature. Dashed lines represent the brightness temperature of the planet assuming zero Bond albedo and a perfect heat redistribution, ε = 1; T = 1570  ±  50 K (left) and no thermal circulation in the atmosphere ε = 0; T = 2000  ±  50 K (right). The grey band covers the albedo values allowed by the 1-σ uncertainty on the occultation depth which is assumed to be the dominant uncertainty.
