1. A method for analyzing an acquired arrangement of object locations that imperfectly conforms to an ideal arrangement of points, the method comprising: in the acquired arrangement of object locations, finding sets of vectors; deriving a composite set of vectors from the sets of vectors; determining vectors between an object location and a number of the object locations, nearest neighboring points; determining whether an object location matches, to an acceptable tolerance, a position specified by the composite set of vectors; and adjusting at least one of the vectors in the composite set to take into account a difference between the position specified and the actual position of the matching object location.
