Systematic Absences of the magnetic space group Cm'c21' (#36.174) in the setting (2a b, -a b, c; 0, 0, 0) of the parent space group P63/mmc (No. 194)
Values of h, k, l:  h integer, k integer, l integer
Warning: h, k, l are referred to the parent-like setting
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 = (Fx,Fx,0)
[Show form of structure factor for every type of reflection]
