How is best fit ellipse drawn to a rusty hole seen at an angle in a photo?

Since this is about recovering historical artifacts, perhaps undigging the following is relevant?

Ellipse through points...no command

Hi, V5 if a number of points are expected to fit a circle (or vice versa !) there is the circle through points option. Obviously if the points are random we dont even contemplate it. Likewise its possible for an elipse to fit points. I see no option for this though and need to plot an elipse through my points which are eliptical. Steve

Then again, the tooth of time has taken its toll on that one and all attachments are lost…
