   The number of reflections in the REFLN list (not the
   DIFFRN_REFLN list) that are significantly intense, satisfying
   the criterion specified by _reflns.threshold_expression. 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. Any special characteristics
   of the reflections included in the REFLN list should be
   described using the item _reflns.details.
