LKPROJ=.TRUE. | .FALSE.
For LKPROJ=.TRUE., VASP will project the orbitals onto the reciprocal space of an alternative unit cell. This unit cell has to be supplied in the file POSCAR.prim, in the usual POSCAR format.
As a first step, the -point projection scheme determines the set , of -points in the irreducible part of the first Brillouin zone of the structure given in POSCAR.prim, for which
Once the set has been determined VASP will compute the following
provides a measure of how strongly the orbital contributes at the point in the reciprocal space of structure POSCAR.prim.
One may, for instance, use this scheme to project the orbitals of a supercell onto the reciprocal space of a generating primitive cell.
N.B.: at the moment the -point projection scheme only works with NPAR=1.
