The total energy is the sum of the following terms:<br>
<br>
one-electron contribution = 4.83378641 Ry<br>
hartree contribution = 1.08429090 Ry<br>
xc contribution = -4.81281466 Ry<br>
ewald contribution = -16.89975858 Ry<br>
---<br>
So: the first term is \sum_v <\psi_v | T + Vion |\psi_v>; the<br>
following terms are the Hartree, exchange correlation, Ewald<br>
contributions to the total energy, as usually defined in the<br>
literature. The sum of eigenvalues is computed but not printed. See<br>
variable "eband" in electrons.f90 and related comments<br>
