Systematic Absences of the magnetic space group P21 (#4.7) in the setting (a, b, c; 0, 0, 0) of the parent space group Pna21 (No. 33)

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

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

[Show form of structure factor for every type of reflection]
