PLAT021

PLAT021 Type_1 Check Expected number of Reflections (Max = 1 Centro, 2 - non-centro)

 The expected number of reflections corresponds to that in the asymmetric
 unit of the Laue group. Expected ratio: less-or-equal 1 for centro symmetric
 structures and less than 2 for non-centrosymmetric structures.
 Reasons to exceed those numbers can be:
  1 - Systematic extinctions not omitted from the obsd data count.
  2 - Refinement with redundant (i.e. not merged/unique) data set.
  3 - SHELXL HKLF 5 Refinement
