Extinction rules for the group P_bba2 (32.140)
Extinctions for general positions (produced by centrings):
   (h k l)     ->      Extinction rule/s:    k = 2n
For h = 1, k = 1, l = 1 : I ≠ 0 F = (Fx, Fy, Fz)
For h = 1, k = 2, l = 1 : I = 0 F = (0, 0, 0)
Extinctions for special positions:
   (0 0 l)          ->      Extinction Rule/s: l any
   (0 k l)          ->      No extra extinctions found
   (h 0 l)          ->      No extra extinctions found
