Available up from VASP version 3.2.
This file contains the projection of the wavefunctions onto spherical harmonics
that are non zero within spheres of a radius RWIGS centered at each ion.
(
).
It is written out only if the LORBIT flag (see section 6.33)
in the INCAR file is set and an appropriate RWIGS (see section 6.32)
has been defined.
