Ths file stores the output of the -point projection scheme (see Sec. 6.82).
It has the following format:
The header section lists the basis vectors of the reciprocal space belonging to the structure
defined in the POSCAR.prim file, and a list of the set of points
the projection scheme has found in the irreducible part of the Brillouin (IBZ) zone of the
aforementioned reciprocal space cell (see Sec. 6.82).
The body of the PRJCAR file lists:
For each band at the body of the PRJCAR lists the index and eigenenergy , followed by one or more rows with a total of NKPTS_PRIME entries , one for each point .
