Category Description

              Data items in the DIFFRN_DATA_FRAME category record
              the details about each frame of data.

              The items in this category were previously in a
              DIFFRN_FRAME_DATA category, which is now deprecated.
              The items from the old category are provided
              as aliases but should not be used for new work.

          /CBF_diffrn_data_frame__details=["DETAILSARRAY"]

    inserts either ARRAYID (if not SECTIONID is specified or the SECTIONID
    into the element of SECTIONIDARRY for this frame and for this detector element (see below)

    inserts BINID
    into the element of BINARYIDARRAY for this frame and for this detector element (see below)

    inserts CENF
    into the element of CENTERARRAY for this frame, for this detector element
    and for the fast center (see below)

    inserts CENS
    into element of CENTERARRAY for this frame, for this detector element
    and for the slow center (see below)

    only one CENTERARRY unit is provided.  If there is variation, the values in
    CENTERARRAY should be rescaled to uniform units.

    _diffrn_data_frame.detector_element_id ELEMENTID -->
    ELEMENTID used to index into the arrays of this category by the ordinal of
    the matching ELEMENTID in DIFFRN_DETECTOR_ELEMENT__id for the fast index
   
    FRAMEID used to index into the arrays of this category by the ordinal of
    the matching ELEMENTID in DIFFRN_DETECTOR_ELEMENT__id for the slow index
    by matching FRAMEID against _diffrn_scan_frame.frame_id and using
    _diffrn_scan_frame.frame_number from the same row.
   
    inserts DETAILS
    into the element of DETAILSARRAY for this frame and for this detector element (see below)

    The arrays created in the mapping have a slow index of the number of frames
    and a fast index of the number of detector elements.  There is a middle index
    for CENTERARRAY in the order fast and then slow.
