Results of the experiment described in 3.4. Top panel: thermal profiles retrieved for each technique (MRCCS: orange, LRSP: blue, CROCODILE: green). The two levels of opacity correspond to the 16 to 84 and the 2 to 98 percentile envelopes of the thermal profile. The legend reports the median and 64 % confidence interval retrieved for the equilibrium temperature. Middle and bottom panel: posterior distributions of the C/O ratio and metallicity Fe/H inferred from the retrieved abundances for each technique. The dashed lines represent the posterior median. The dashed red line shows the ground truth in every panel.
