h_s computes sin(theta) / lambda for a given reflection.

function call

r = h_s(h: ndarray,cell : dict, kwargs : dict)

Variable	Type	Description
h	ndarray; dtype = float32; shape = 3 or ndarray; dtype = int32; shape = :	Reflection index. Shape = 3 for real index, 3+ n for integer index. The integer form must be used with optional arguments.
cell	dict	Unit cell. It must be a dictionary of type cell_g_type or cell_gls_type. It can be generated with the function set_crystal_cell.
kwargs	dict	Optional arguments. Keywords are: nk, kv.
	nk	int	Number of propagation vectors
	kv	ndarray; dtype = float32; shape = (nk,3)	Propagation vectors.
r	tuple	The tuple returned by the function. r[0] : int, error code. If non-zero, an error has occurred. r[1] : str, error message. r[2]: float, sin(theta) / lambda for reflection h.
