<h1>_diffrn_detector_element.center[2]</h1><b>Name:</b><br /><tt class="cifdefinition">'_diffrn_detector_element.center[2]'</tt>
<p><b>Definition:</b></p><pre class="cifdefinition">
The value of _diffrn_detector_element.center[2] is the Y
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
<a href="Idiffrn_data_frame.center_slow.html" class="itemlink">_diffrn_data_frame.center_slow</a>
which is referenced to the detector coordinate system and not
directly to the laboratory coordinate system should be used
instead.
