Figure 3.

Adaptive measurement process illustration. The graph shows the convergence of the z value of a typical point on a flat sample area (point A) and close to a steep slope (point B) if the iterative refinement process is not stopped by the precision criterion. The precision criterion is used to stop refinements locally as shown in the inset.
