Moreover, if distortions are significant, the true probe position may be quite different from the nominal position.
Δ a is the elastic strain vector of the compliant mechanism from its nominal position p i,g.
However, for more complicated scan patterns, it is also necessary to specify the (nominal) position where each data point was acquired.
