XmlmmCIF equivalent: diffrn_standard_refln Data items in the DIFFRN_STANDARD_REFLN category record details about the reflections treated as standards during the measurement of a set of diffraction intensities. Note that these are the individual standard reflections, not the results of the analysis of the standard reflections. XmlmmCIF equivalent: diffrn_standard_refln/index_h Miller index h of a standard reflection used in the diffraction measurement process. XmlmmCIF equivalent: diffrn_standard_refln/index_k Miller index k of a standard reflection used in the diffraction measurement process. XmlmmCIF equivalent: diffrn_standard_refln/index_l Miller index l of a standard reflection used in the diffraction measurement process. XmlmmCIF equivalent: diffrn_standard_refln/diffrn_id This data item is a pointer to _diffrn.id in the DIFFRN category. XmlmmCIF equivalent: diffrn_standard_refln/code The code identifying a reflection measured as a standard reflection with the indices _diffrn_standard_refln.index_h, _diffrn_standard_refln.index_k and _diffrn_standard_refln.index_l. This is the same code as the _diffrn_refln.standard_code in the DIFFRN_REFLN list.
