   For each reflection class, the number of significantly intense
   reflections (see _reflns_threshold_expression) in the _refln_
   list (not the _diffrn_refln_ list). This 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. Special characteristics of the reflections
   included in the _refln_ list should be given in the item
