Abstract
We present a fast code to fit circular arcs to measured points. Our algorithm is based on an explicit solution of a non-linear least-squares problem to fit the circle curvature, direction and position parameters. The code includes error estimation of the circle parameters as well as the transformation of parameters and error matrix to another point of reference. The formalism is valid for any arc lenght up to a full circle.
Title of program: CIRCLEFIT
Catalogue Id: ACBZ_v1_0
Nature of problem
Least squares parametrisation and error estimation of circular arc with measured points.
