_diffrn_scan_axis.reference_displacement
Name:_diffrn_scan_axis.reference_displacement
Definition:
The setting of the specified axis in millimetres against which measurements of the reference beam center and reference detector distance should be made. In general, this will agree with _diffrn_scan_frame_axis.reference_displacement. If the individual frame values vary, then the value of _diffrn_scan_axis.reference_displacement will be representative of the ensemble of values of _diffrn_scan_frame_axis.reference_displacement (e.g. the mean).
