# _diffrn_scan_axis.displacement_increment

Name:
`'_diffrn_scan_axis.displacement_increment'`

Definition:

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