Table 2.

A comparison of the measurements in cross-sections by means of System 1 with the reference measurement. dx is the difference between the tested and the reference measurement in the plane of the clearance gauge in the horizontal direction; dy is the difference between the tested and the reference measurement in the plane of the clearance gauge in the vertical direction.
