XmlmmCIF equivalent: diffrn_scale_group Data items in the DIFFRN_SCALE_GROUP category record details about the reflections used to scale the diffraction intensities. Scaling groups might, for instance, correspond to each film in a multi-film data set, or each crystal in a multi-crystal data set. XmlmmCIF equivalent: diffrn_scale_group/I_net The scale for a specific measurement group which is to be multiplied with the net intensity to place all intensities in the DIFFRN_REFLN or REFLN list on a common scale. XmlmmCIF equivalent: diffrn_scale_group/code The value of diffrn_scale_group.code must uniquely identify a record in the DIFFRN_SCALE_GROUP list. Note that this item need not be a number; it can be any unique identifier.
