WebFitting standard shapes or curves to incomplete data (which represent only a small part of the curve) is a notoriously di–cult problem. Even if the curve is quite simple, such as an ellipse or a circle, it is hard to reconstruct it from noisy data sampled along a short arc. Here we study the least squares flt (LSF) of circular
