Temperature–pressure profiles of the atmosphere that we use to explore the dependence on temperature in Section 3.6. The green line represents the fiducial profile, which is calculated by the use of the analytical formula of Guillot (2010). Also shown is the profile for the irradiation temperature T_irr higher by 500 K than the fiducial value of 790 K, that is, 1290 K (red line), with the other parameters unchanged from the fiducial values.
