JPL#39 (23-01-08) : ffa2a814-c675-4682-a6fa-9079a9d9c684 [db: observed]

Using prediction ffa2a814-c675-4682-a6fa-9079a9d9c684 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 174 x 46 km
a',b' = 87.1, 23.2 km
X0,Y0 = -1214.9, 45.8 km
Mean diameter = 90 km

From 3 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.
