Parameter	Prior	Input

Guillot, free chemistry
log ɡ	𝒰 (2.0, 5.5)	4.0
R_pl	𝒩 (1.0 R_jup, 0.2 R_jup)	1.0 R_jup
T_int	𝒰 (300 K, 2000 K)	750 K
T_equ	𝒰 (0 K, 300 K)	100 K
γ	𝒩 (1, 0.2)	0.5
log κ_IR	𝒰 (−3.0, 1.0)	−1.0
log	𝒰 (−7.0, 0.0)	−1.5
log X_CO	𝒰 (−7.0, 0.0)	−2.0

Notes. 𝒰(a, b) denotes uniform priors with bounds a and b, and 𝒩 (µ, σ) denotes a normal distribution centred at a mean µ with standard deviation σ. The final column indicates the true values of the spectrum injected into the IFS cubes.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
