ODDONLYGW = [logical]
Default: ODDONLYGW = .FALSE. 

Description: ODDONLYGW allows to avoid the inclusion of the point in the evaluation of response functions (in GW calculations).


The independent particle polarizability is given by:

If the point is included in the summation over , convergence is very slow for some materials (e.g. GaAs).

To deal with this problem the flag ODDONLYGW has been included. In the automatic mode, the -grid is given by (see Sec. \ref{sec:autok}):
