Extinction rules for the group P_Bmc2_1 (26.75)

Extinctions for general positions (produced by centrings):

(h k l) -> Extinction rule/s: h + l = 2n

    For  h = 1, k = 1, l = 1 :      I = 0       F = (0, 0, 0)

    For  h = 1, k = 1, l = 2 :      I ≠ 0       F = (Fx, Fy, Fz)

    For  h = 2, k = 1, l = 1 :      I ≠ 0       F = (Fx, Fy, Fz)

    For  h = 2, k = 1, l = 2 :      I = 0       F = (0, 0, 0)

Extinctions for special positions:

   (0 0 l)          ->      No extra extinctions found

   (0 k l)          ->      No extra extinctions found

   (h 0 l)          ->      No extra extinctions found
