ReciprocalLatticePoint

class diffsims.crystallography.ReciprocalLatticePoint(phase, hkl)

Bases: object

[Deprecated] Reciprocal lattice point (or crystal plane, reflector, g, etc.) with Miller indices, length of the reciprocal lattice vectors and other relevant structure_factor parameters.

Notes

Deprecated since version 0.5: Class ReciprocalLatticePoint is deprecated and will be removed in version 0.6. Use ReciprocalLatticeVector instead.
