JPL#121 (23-01-08) : 1a6c0e19-500c-4ca3-9e73-1191a842f836 [db: observed]

Using prediction 1a6c0e19-500c-4ca3-9e73-1191a842f836 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 121 x 93 km
a',b' = 60.5, 46.6 km
X0,Y0 = 239.6, 7.1 km
Mean diameter = 106 km

From 8 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.
