Ellipse and circular profile fits to the timings (chords)

 Auto-Fit Result:
Size = 115 x 69 km
a',b' = 57.5, 34.7 km
X0,Y0 = 1995.1, 10.6 km
Mean diameter = 89 km

From 3 chords (VID,CCD)








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.

Check Johnston Archive for satellites.
