JPL#165 : 29252c50-ddb0-11f0-547e-26647fbfac4a [db: observed]

Using prediction 29252c50-ddb0-11f0-547e-26647fbfac4a for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 75 x 36 km a',b' = 37.6, 17.9 km X0,Y0 = -2517.5, 21.5 km Mean diameter = 52 km From 3 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.
