302
303    n = band index.
304  Emf = "inner" mean-field energy eigenvalue used to construct Sigma(E),
305        read from WFN_inner.
306   Eo = "outer" mean-field energy eigenvalue where we center the evaluation
307        frequency grid {E} of Sigma(E). Defaults to Emf, unless
308        you use WFN_outer and eqp_outer.dat / scissors_outer.
309  Vxc = exchange-correlation pot., calculated from VXC or read from vxc.dat.
310    X = bare exchange.
311   SX = screened exchange contrib. to Sigma(E) at energy E=Eo
312   CH = Coulomb hole contrib. to Sigma(E) at energy E=Eo
313  Cor = SX-X + CH = correlation portion of Sigma(E) at energy E=Eo.
314  Sig = X + Cor = self energy, Sigma(E), at energy E=Eo.
315 Eqp0 = Emf - Vxc + Sig(Eo)
316        (Eqp0 is the on-shell QP energy, not recommended for direct usage)
317 Eqp1 = Eqp0 + (dSig/dE) / (1 - dSig/dE) * (Eqp0 - Eo)
318        (Eqp1 is the off-shell QP energy obtained by solving the linearized
319         Dyson`s equation, and is the recommended quantity for QP properties.)
320  Znk = quasiparticle renormalization factor
321
322 Notes on the static remainder:
323 - Unprimed values, such as Eqp0, are evaluated WITH the static remainder
324 - Primed values, such as Eqp0`, are evaluated WITHOUT the static remainder
325
326 Notes on the finite_difference_form from sigma.inp file:
327   none    : -2 => dSig/dE = 0 (skip the expansion)
328   backward: -1 => dSig/dE = (Sig(Eo) - Sig(Eo-dE)) / dE
329   central :  0 => dSig/dE = (Sig(Eo+dE) - Sig(Eo-dE)) / (2*dE)
330   forward :  1 => dSig/dE = (Sig(Eo+dE) - Sig(Eo)) / dE
331   default :  2 => forward for diagonal and none for off-diagonal
332   dE is finite_difference_spacing from Sigma.inp file.
333   We are using the form #2 with dE = 1.000 eV.
334
335 General notes:
336 - All energies are reported here in eV.
337 - Both Emf and Vxc contain the average pot. Vxc0, so Vxc0 doesn`t affect Sigma.
338 - Eqp1 and Eqp0 are Eqs. (36-37) from Hybertsen & Louie PRB 34 5390.
339 - We recommend you use Eqp1 for QP properties of materials.

341================================================================================
342
343
344WARNING: |Eqp0 - Eo| > finite_difference_spacing. Linear extrapolation for eqp1
345may be inaccurate. You should test the validity of eqp1 by rerunning the
346calculation with the self energy evaluated at the eqp0 energies. For that,
347use the eqp_outer.dat file, created with eqp.py script and point WFN_outer to
348WFN_inner, if you were not already using WFN_outer.
