Item Description
For each reflection class, the number of significantly intense
reflections (see _reflns.threshold_expression) in the REFLN

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.
