Notes. All of them are simulated with [M/H] = 1 and C/O = 0.5. The volume mixing ratio (in log scale) of molecules present in the Exo-REM models are given for each of the simulated planets at the top of the atmosphere (log X_mol at 10⁻² bar). Other molecules used in the model have a volume mixing ratio of less than 10⁻²⁰.
