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 _reflns_special_details.
