Comparison between the results obtained from the retrieval performed for the case of a hot-Jupiter around a G star when the mass is known with an uncertainty of 40 (in green) and of 10% (in magenta) as well as when is totally unknown (in orange) as a function of cloud pressure. In the gray area, we report the results obtained for a P_clouds = 10⁻³ bar, assuming noise decreased by a factor of two. The size of the box and the error bar represent the points within 1σ and 2σ of the median of the distribution (highlighted with solid lines), respectively. Blue line is the real value.
