AGGAX

AGGAX = [real] 

Default: AGGAX	= 1.0-AEXX	if LHFCALC=.TRUE.
	= 1.0	if LHFCALC=.FALSE.

Description: AGGAX is a parameter that multiplies the gradient correction in the GGA exchange functional.

---

AGGAX can be used as the fraction of gradient correction in the GGA exchange in a Hartree-Fock/GGA hybrid functional.

Important: AGGAX can be used only if LHFCALC=.TRUE.

Mind: AGGAX is implemented for all functionals listed at GGA except AM05. AGGAX is implemented for the functionals from Libxc (see LIBXC1 for details).
