Best-fit model for a GCM’s synthetic atmosphere with TiO and VO as optical absorbers. TauREx 2D retrieval code found two possible solutions for this case (the red and the blue one for the solution with β = 4.3 and β = 10.0 degrees, respectively). The solutions from the ID retrieval using an isothermal profile and a four PT point profile are shown in yellow and green, respectively.
