Ellipse and circular profile fits to the timings (chords)

 Auto-Fit Result:
Size = 88 x 60 km
a',b' = 44.0, 29.9 km
X0,Y0 = -1153.4, 23.5 km
Mean diameter = 73 km

From 16 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.

Check Johnston Archive for satellites.
