Data items in the DIFFRN_DETECTOR_ELEMENT category record the details about spatial layout and other characteristics of each element of a detector which may have multiple elements. In most cases, giving more detailed information in ARRAY_STRUCTURE_LIST and ARRAY_STRUCTURE_LIST_AXIS is preferable to simply providing the centre of the detector element.
