132 Parallelization report:
133 - Using 24 processor(s), 1 pool(s), 24 processor(s) per pool.
134 - Each pool is computing 37 diagonal sigma matrix element(s).
135 - Each pool is computing 0 off-diagonal sigma matrix element(s).
136 - Each pool is holding 16 to 21 band(s).
137 - Note: distribution is not ideal because the total number of bands
138   (499) is not divisible by the number of processors per pool (24).

334    n = band index.
335  Emf = "inner" mean-field energy eigenvalue used to construct Sigma(E),
336        read from WFN_inner.
337   Eo = "outer" mean-field energy eigenvalue where we center the evaluation
338        frequency grid {E} of Sigma(E). Defaults to Emf, unless
339        you use WFN_outer and eqp_outer.dat / scissors_outer.
340  Vxc = exchange-correlation pot., calculated from VXC or read from vxc.dat.
341    X = bare exchange.
342   SX = screened exchange contrib. to Sigma(E) at energy E=Eo
343   CH = Coulomb hole contrib. to Sigma(E) at energy E=Eo
344  Cor = SX-X + CH = correlation portion of Sigma(E) at energy E=Eo.
345  Sig = X + Cor = self energy, Sigma(E), at energy E=Eo.
346 Eqp0 = on-shell QP energy = Emf - Vxc + Sig(Eo)
347        Eqp0 is *not* the recommended quantity to use for QP properties.
348 Eqp1 = off-shell solution to the linearized  Dyson`s equation
349      = Eqp0 + (dSig/dE) / (1 - dSig/dE) * (Eqp0 - Eo),
350        or a full linear interpolation if more freq. points where computed.
351        Eqp1 is the recommended quantity to use for QP properties.
352  Znk = quasiparticle renormalization factor
353
354 Notes on the finite_difference_form from sigma.inp file:
355   none    : -2 => dSig/dE = 0 (skip the expansion)
356   backward: -1 => dSig/dE = (Sig(Eo) - Sig(Eo-dE)) / dE
357   central :  0 => dSig/dE = (Sig(Eo+dE) - Sig(Eo-dE)) / (2*dE)
358   forward :  1 => dSig/dE = (Sig(Eo+dE) - Sig(Eo)) / dE
359   default :  2 => forward for diagonal and none for off-diagonal
360   dE is finite_difference_spacing from Sigma.inp file.
361   We are using the form #2 with dE = 1.000 eV.
362
363 General notes:
364 - All energies are reported here in eV.
365 - Both Emf and Vxc contain the average pot. Vxc0, so Vxc0 doesn`t affect Sigma.
366 - Eqp1 and Eqp0 are Eqs. (36-37) from Hybertsen & Louie PRB 34 5390.
367 - We recommend you use Eqp1 for QP properties of materials.

371
372WARNING: |Eqp0 - Eo| > finite_difference_spacing. Linear extrapolation for eqp1
373may be inaccurate. You should test the validity of eqp1 by rerunning the
374calculation with the self energy evaluated at the eqp0 energies. For that,
375use the eqp_outer.dat file, created with eqp.py script and point WFN_outer to
376WFN_inner, if you were not already using WFN_outer.
