Extinction rules for the group Pmna (53.321)
Extinctions for general positions (produced by centrings):
   Primitive unit cell: No extinctions
Extinctions for special positions:
   (h 0 0)          ->      Extinction Rule/s: h any
   (0 k 0)          ->      Extinction Rule/s: k any
   (0 0 l)          ->      Extinction rule/s:    l = 2n
For l = 1 : I ≠ 0 F = (Fx, 0, 0)
For l = 2 : I = 0 F = (0, 0, 0)
   (0 k l)          ->      No extra extinctions found
   (h 0 l)          ->      No extra extinctions found
   (h k 0)          ->      No extra extinctions found
