Category: reflns_class

Data type: numb

Must appear in a looped list containing '_reflns_class_code'

Enumeration range: 0.0 -> infinity


   For each reflection class, the number of significantly intense
   reflections (see _reflns_threshold_expression) in the _refln_
   list (not the _diffrn_refln_ list). It may include Friedel
   equivalent reflections (i.e. those which are symmetry equivalent
   under the Laue symmetry but inequivalent under the crystal
   class)  according to the nature of the structure and the
   procedures used. The special characteristics of the reflections
   included in the _refln_ list should be given in the item
