The total energy is computed for a given broadening quantified with some artificial temperature when setting the calculator. Even so this is an artificial temperature introduced to speed up convergence of SCF, there is an entropy term -T*S in the corresponding free energy expression ('Total free energy' at T<> 0 K). The true ground state energy (i.e., at T=0 K) is given by 'Total energy (broadening->0)' .
