Name:
`'_diffrn_scan_frame_axis.reference_displacement'`

Definition:

            The setting of the specified axis in millimetres for this
                   frame against which measurements of the reference beam center
                   and reference detector distance should be made.

                   This is normally the same for all frames, but the
                   option is provided here of making changes when
                   needed.

                   If not provided, it is assumed to be equal to
                   _diffrn_scan_frame_axis.displacement.
