PT profile retrieved compared to the input PT profile. In both scenarios, with and without TiO and VO, the PT profile with temperature inversion has been used. The night, terminator, and day-side PT profile of both the input (continuous line) and the retrieved models (dashed lines) are in blue, purple, and red, respectively. In the upper and lower part, we show the first and the second solution from the 2D retrievals, respectively. The solutions from a ID retrieval using the four PT point profile (only for the GCM case with optical absorbers) and the isothermal PT profile are in green and yellow, respectively.
