Dear Andrew,

The attached code assumes the ring is more or less in the centre and will try to find the best fitting circle. It also uses the Color Threshold to find the green areas but you probably have already better code to collect this info but maybe the first part is useful to find the ring in the image. At the moment you manually have to open an image.

Best wishes

Kees

Dear Kees,

Yes the rings are more or less in the same place.

Thank you for your comments, Charles.  Am I supposed to draw the circle on the last black and white image that pops up, titled "Results of a (green) (25%)?  or on the original image?
