Extinction rules for the group P_Cmna (53.335)
Extinctions for general positions (produced by centrings):
   (h k l)     ->      Extinction rule/s:    h + k = 2n
For h = 1, k = 1, l = 1 : I = 0 F = (0, 0, 0)
For h = 1, k = 2, l = 1 : I ≠ 0 F = (Fx, Fy, Fz)
For h = 2, k = 1, l = 1 : I ≠ 0 F = (Fx, Fy, Fz)
For h = 2, k = 2, l = 1 : I = 0 F = (0, 0, 0)
Extinctions for special positions:
   (h 0 0)          ->      Extinction Rule/s: h any
   (0 k 0)          ->      Extinction Rule/s: k any
   (0 0 l)          ->      No extra extinctions found
   (0 k l)          ->      No extra extinctions found
   (h 0 l)          ->      No extra extinctions found
   (h k 0)          ->      No extra extinctions found
