JPL#46 (23-01-08) : e97c20ca-2f1a-4cf2-bc61-2b7fad43f985 [db: observed]

Using prediction e97c20ca-2f1a-4cf2-bc61-2b7fad43f985 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: X0,Y0 = 692.9, -11.0 km Circular diameter = 40 km From 2 chords (VID) Chords to ignore: Fill: Grid: Show (close) miss chords: 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.
