JPL#61 (23-01-08) : a8477b25-ed55-493f-9085-6237a97875a7 [db: observed]

Using prediction a8477b25-ed55-493f-9085-6237a97875a7 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 281 x 88 km
a',b' = 140.5, 43.9 km
X0,Y0 = -2352.8, 3.3 km
Mean diameter = 157 km

From 4 chords (VID,CCD,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.
