WebAug 26, 2024 · For example, to fit a circle of radius 1000 to your data would presumably result in a centre some way off the the right, as you have more points on the left side of the circle, which would get more weight in a least squares type calculation. Or you could use the method you have, but ignore the fitted radius, to get a centre that is not biased ... WebI devised a way to do this which involves the following steps: Create a table with x and y values.

"WebNote that the fit here is particularly poor due to the middle $(x_0,y_0)$ point being offset to the left from the bulk of the data, since I currently always include that center point in the arc. This still works better than fitting with the moments, though, as it imposes that the points cover a roughly 20 degree portion of the circle. " - Fit circle to points
