| 1. A device for indicating at least one of an orbit of, and a deviation from a nominally round surface of a mechanical object,
the device comprising:
a processor; and
output means for outputting a deviation profile,
wherein the processor for generating the deviation profile based on distance data sets covering the nominally round surface;
each distance data set comprising at least three distances, measured in a direction of rotation, to the nominally round surface
and related to an angle, the at least three distances having been measured at distance measuring angles; and the processor
for indicating the deviation profile using the output means wherein the distance measuring angles are selected such that the
locations of zeroes in a transfer function used in generating the deviation profile are satisfactory.
