RFit implements an algorithm estimating ring parameters over a set of scattered points (usually given by RICH detectors). It is based on minimization of a deviation between a sought ring an a given data points. RFit uses MINUIT package to perform the minimization. It supports both standard and robust approaches.

Program implementation is a special case of the Fitter package.
