Ellipse and circular profile fits to the timings (chords)

 Auto-Fit Result:
Size = 154 x 145 km
a',b' = 77.0, 72.5 km
X0,Y0 = -944.2, 34.1 km
Mean diameter = 149 km

From 11 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.

Check Johnston Archive for satellites.
