Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 67 x 57 km
a',b' = 33.3, 28.6 km
X0,Y0 = 1298.7, 34.0 km
Mean diameter = 62 km

From 3 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).
