Item Description

For each reflection class, the number of significantly intense reflections (see _reflns.threshold_expression) in the REFLN list (not the DIFFRN_REFLN list). 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.
