Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
X0,Y0 = 3429.1, 35.7 km
Circular diameter = 13 km

From 2 chords (VID)

You can enter space separated chord numbers (example: 11 4 8) or a method like VIS to ignore all visual timings, or a time source like RAD and NTP (but not GPS).
If the plot disappears, then there are less than 2 chords left (too much ignored, go back with browser).
