JPL#74 (23-01-08) : d1a0e00d-47e7-48b1-828c-77e347aaf81e [db: observed]

Using prediction d1a0e00d-47e7-48b1-828c-77e347aaf81e for map and profile fit

Ellipse and circular profile fits to the timings (chords)

 Auto-Fit Result:
Size = 354 x 21 km
a',b' = 177.1, 10.5 km
X0,Y0 = 209.3, 23.0 km
Mean diameter = 86 km

From 3 chords (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.
