Dear All,

Why is the ion charge in OUTCAR afer SCF calculation so not accurate? For exaple, when I sdudied GaAs, and I found the As ion charge is around 2.8 e which is far from its valance electron number:5.

It there any way to improve it. By the way, I tried to increase the Wig-Seits radius, and it did not help much.

Thanks in advance.
