First row: Best-fit models for our joint retrievals of WASP-80 b JR1 (equilibrium chemistry; left panel) and JR1* (free chemistry; right panel). Second row: Posterior distribution function (PDF) of the retrieved masses for JR1 and JR1*. Dashed and dotted lines indicate the mean and standard deviations of the PDFs. White circles indicate the observed data with their respective uncertainties in all four panels. Third and fourth rows: Best-fit model for our joint retrieval JR6.
