JPL#103 (23-01-08) : 35df6ebd-e583-48e4-a5ac-8c1486c6b974 [db: observed]

Using prediction 35df6ebd-e583-48e4-a5ac-8c1486c6b974 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result:
Size = 148 x 136 km
a',b' = 74.0, 67.8 km
X0,Y0 = 1481.4, 123.1 km
Mean diameter = 142 km

From 4 chords (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.
