Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 163 x 115 km
a',b' = 81.6, 57.3 km
X0,Y0 = 569.2, 20.6 km
Mean diameter = 137 km

From 18 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.
