Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 47 x 31 km
a',b' = 23.6, 15.6 km
X0,Y0 = 1543.5, 28.2 km
Mean diameter = 38 km

From 5 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.
