Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 114 x 19 km
a',b' = 57.0, 9.7 km
X0,Y0 = 530.0, 55.5 km
Mean diameter = 47 km

From 5 chords (VID,VIS)

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.
