Retrieved parameters and temperature structure of 2M0355 using the nominal model. Upper right panel: retrieved temperature-pressure confidence envelopes. The coloured regions represent 1σ, 2σ, 3σ confidence envelopes. The black dotted line shows the flux average of the emission contribution function. The gray dashed line represents the condensation curve of MgSiO₃ clouds. Lower left panel: posterior distributions of parameters. The vertical dashed lines denote the 5%, 50%, 95% quantiles (90% uncertainties) of the distribution.
