Magnetic diffraction Systematic Absences for the group Cm'c21' (#36.174)
For this space group, BNS and OG settings coincide.
Its label in the OG setting is given as: Cm'c21' (#36.3.251)

Values of h, k, l:  h integer, k integer, l integer

Systematic absences for general reflections (produced by centrings):

Diffraction vector type:   (h k l)     ->      Systematic absence:    h + k = 2n + 1

Systematic absences for special reflections:

Diffraction vector type:   (0 0 l)     ->      Systematic absence:    l = 2n + 1

For l = 1: I = 0 F = (0,0,Fz)
For l = 2: I /= 0 F = (0,Fy,0)
