Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 79 x 67 km
a',b' = 39.7, 33.7 km
X0,Y0 = -3866.4, 7.3 km
Mean diameter = 73 km

From 3 chords (CCD,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.
