KGAMMA = [logical]
Default: KGAMMA = .FALSE.
Description: This tag controls whether the frequency dependent self-energy is calculated or not.
If LSELFENERGY=.FALSE., QP shifts are evaluated. This is the default behavior.
If LSELFENERGY=.TRUE., the frequency dependent self-energy is evaluated. Evaluation of QP shifts is bypassed in this case.
