A positioning or measurement error caused by parasitic rotations when a misalignment exists between the measurement axis and the point of interest. By reducing either parasitic rotations or the offset of misalignment, or both, the abbe error can be minimized. The abbe error can be estimated as: δ = ι * α where δ is positioning error, ι is the offset of misalignment between the measurement axis and the point of interest, and α is the angle of parasitic rotation.
