USE
get_h_info returns information about a particular reflection. Information consists of four numbers. The first three specifies if the reflection is allowed (0) or absent (1) by lattice, nuclear and magnetic constraints. The fourth number refers to the character of the reflection: pure nuclear (0), pure magnetic (1) and nuclear + magnetic (2).
function call
r = get_h_info(h: ndarray,spg : dict, mag : bool)
| Variable | Type | Description |
|---|---|---|
| h | ndarray; dtype = int32; shape = : | Reflection index. Shape = 3 + n, where n is the number of propagation vectors. |
| spg | dict | Space group. It must be a dictionary of type spg_type or superspacegroup_type. It can be generated with the function set_spacegroup. |
| mag | bool | True if magnetic scattering must be considered. |
| 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]: ndarray; dtype = int32; shape = 4, information about h. |
