Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 191 x 125 km
a',b' = 95.3, 62.7 km
X0,Y0 = -1616.6, 27.5 km
Mean diameter = 155 km

From 4 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).

Check SiMDA for size and mass data.
