Claim 19:
20. The system of claim 19, wherein the operations further comprise:
determining sinusoidal measurement errors in measurements of the angular positions of the first platform indicated by the encoder output signals during the at least one complete rotation;
based on a determination that the sinusoidal measurement errors are associated with a concentricity of the first magnetic field at the given surface of the second platform relative to the axis of rotation of the first platform, identifying a first misalignment in a relative arrangement of the first platform and the second platform; and
based on a determination that the sinusoidal measurement errors are associated with a circularity of the arrangement of the plurality of magnets, identifying a second misalignment in the arrangement of the plurality of magnets around the axis of rotation of the first platform.
