            Defaults are None and they are automatically determined.
        use_tetrahedron_method : float, optional
            Use tetrahedron method when this is True. When sigma is set,
            smearing method is used.
        direction : array_like, optional
            Specific projection direction. This is specified three values
            along basis vectors or the primitive cell. Default is None,
            i.e., no projection.
        xyz_projection : bool, optional
            This determines whether projected along Cartesian directions or
            not. Default is False, i.e., no projection.
