T_int–T_eq and P_RCB –T_eq diagrams in the upper and lower panels, respectively. The dark and light shaded regions present the 68 and 95% credible intervals. Although the analytical approach overestimates the internal temperature at T_eq between 1000 and 1800 K, there is a good agreement at T_eq < 1000 K and T_eq > 1800 K. Due to the increase in the internal temperature with equilibrium temperature, the P_RCB moves to lower pressures with increasing T_eq, reaching up to ~3 bar for the most irradiated planets.
