double complex offsite_wave_overlap	(	double *	dcoord,
		double *	r1,
		double *	f1,
		double **	spline1,
		int	size1,
		double *	r2,
		double *	f2,
		double **	spline2,
		int	size2,
		double *	lattice,
		int	l1,
		int	m1,
		int	l2,
		int	m2
	)

Given dcoord: difference between site locations (R2-R1); r1, the radial grid, size size1, of the function f1 interpolated with spline1; likewise for f2; the lattice in which the sites are located, and the angular quantum numbers of the two functions, finds the overlap integral of f1 and f2.

double complex reciprocal_offsite_wave_overlap	(	double *	dcoord,
		double *	k1,
		double *	f1,
		double **	s1,

		int	l1,
		int	m1,
		int	l2,
		int	m2
	)

Given dcoord: difference between site locations (R2-R1); k1, the reciprocal radial grid, size size1, of the function f1 interpolated with spline1; likewise for f2; the lattice in which the sites are located, and the angular quantum numbers of the two functions, finds the overlap integral of f1 and f2 in reciprocal space.
