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.
