# _diffrn_scan_axis.displacement_rstrt_incr

Name:
`'_diffrn_scan_axis.displacement_rstrt_incr'`

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).
