   The number of 'observed' reflections, in the _refln_ list (not
   the _diffrn_refln_ list). The observed reflections satisfy the
   threshold criterion specified by _reflns_threshold_expression
   (or the deprecated _reflns_observed_criterion). They may include
   Friedel equivalent reflections 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 _reflns_special_details.
