After updating, re-scan the calibration target. The spacing between
features should be approximately the same across the scan range.
X Hysteresis
Place a vertical cursor at the same location in the Trace and Retrace
images. The cursor should cross the same features in both images. If this
is not the case, as in Figure 98, increase the X Hysteresis value and
re-scan. Alignment should be consistent across the full range of the
x-axis. Several iterations may be necessary to align all edges in the trace
and retrace images.
