Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 162 x 104 km
a',b' = 80.8, 52.1 km
X0,Y0 = 1039.8, -11.1 km
Mean diameter = 130 km

From 4 chords (VID,DRS)

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).
