Category Description

     Data items in the DIFFRN_SCAN_FRAME_AXIS category describe the
     settings of axes for particular frames.  Unspecified axes are
     assumed to be at their zero points.  If, for any given frame,
     nonzero values apply for any of the data items in this category,
     those values should be given explicitly in this category and not
     simply inferred from values in DIFFRN_SCAN_AXIS.

    note that @units="mm" or @units="deg" should also be specified.
   
    The dimensions of the array depend on np (the number of frames = the
    value of _diffrn_scan.frames)
   
    either DISP OR ANGLE is inserted as the i-th element
    counting from 1 in AXISID where i is the value of
    _diffrn_scan_frame.frame_number for which the value
    of _diffrn_scan_frame.frame_id agrees with the
    value of _diffrn_scan_frame_axis.frame_id
   
    The remaining tags similarly populate the attribute arrays
