Item Description

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.
