JPL#81 : 1023aa70-ddb4-11f0-547e-9370ed1f1ac6 [db: observed]

Using prediction 1023aa70-ddb4-11f0-547e-9370ed1f1ac6 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 101 x 69 km a',b' = 50.6, 34.4 km X0,Y0 = 2204.1, 22.7 km Mean diameter = 83 km From 4 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.
