JPL#145 : 7ef4b1f0-ddb5-11f0-547e-5d58bfffca4d [db: observed]

Using prediction 7ef4b1f0-ddb5-11f0-547e-5d58bfffca4d for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 112 x 91 km a',b' = 55.8, 45.3 km X0,Y0 = 1822.9, 27.6 km Mean diameter = 100 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.
