Ellipse and circular profile fits to the timings (chords)

 Auto-Fit Result:
Size = 513 x 218 km
a',b' = 256.4, 108.9 km
X0,Y0 = -352.5, 892.3 km
Mean diameter = 334 km

From 6 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.
