Comparison of CFBDSIR2149 full spectrum at R = 225 (red) with various models (black). Upper left: Burrows Sudarsky Lunine 2003 model for a 100 Myr, 7 M_jup planet (i.e. T_eff  ~  750 K, log g  ~  4.1) with no clouds. Upper right: BT-Settl models for T_eff  =  650 K and log g = 3.75. Lower left: Madhusudhan et al. (2011) cloudy “E” model at T_eff  =  700 K, log = 4.0 and 60 μm enstatite particles in clouds. Lower right: Madhusudhan et al. (2011) cloudy “A” model at T_eff  =  700 K, log = 4.0 and 100 μm particles in clouds.
