Magnetic diffraction Systematic Absences for the group Cmcm' (#63.461)
For this space group, BNS and OG settings coincide.
Its label in the OG setting is given as: Cmcm' (#63.5.515)

Systematic absences for general reflections (produced by centrings):

Systematic absences for special reflections:

For l = 1:      I /= 0       F = (Fx,0,0)

For l = 2:      I = 0       F = (0,0,0)

Introduce the new basis vectors of the reciprocal lattice:

a*' =	a* +	b* +	c*
b*' =	a* +	b* +	c*
c*' =	a* +	b* +	c*
