Category Description

              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.
