Definition:
The increment for each step for the specified axis in millimetres. In general, this will agree with _diffrn_scan_frame_axis.displacement_rstrt_incr. The sum of the values of _diffrn_scan_frame_axis.displacement, _diffrn_scan_frame_axis.displacement_increment and _diffrn_scan_frame_axis.displacement_rstrt_incr is the angular setting of the axis at the start of the integration time for the next frame relative to a given frame and should equal _diffrn_scan_frame_axis.displacement for this next frame. If the individual frame values vary, then the value of _diffrn_scan_axis.displacement_rstrt_incr will be representative of the ensemble of values of _diffrn_scan_frame_axis.displacement_rstrt_incr (e.g. the mean).
