_diffrn_detector_element.center[1]

Name:
'_diffrn_detector_element.center[1]'

Definition:

       The value of _diffrn_detector_element.center[1] is the X
              component of the distortion-corrected beam centre in
              millimetres from the (0, 0) (lower-left) corner of the
              detector element viewed from the sample side.

              The X and Y axes are the laboratory coordinate system
              coordinates defined in the AXIS category measured
              when all positioning axes for the detector are at their zero
              settings.  If the resulting X or Y axis is then orthogonal to the
              detector, the Z axis is used instead of the orthogonal axis.

              Because of ambiguity about the setting used to determine this 
              center, use of this data item is deprecated.  The data item
              _diffrn_data_frame.center_fast
              which is referenced to the detector coordinate system and not
              directly to the laboratory coordinate system should be used 
              instead.
