JPL#140 : 38a3b200-ddb0-11f0-547e-e52cbfee1c16 [db: observed]

Using prediction 38a3b200-ddb0-11f0-547e-e52cbfee1c16 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 188 x 80 km a',b' = 94.1, 39.8 km X0,Y0 = -458.7, 12.0 km Mean diameter = 122 km From 5 chords (VID,CCD) 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.
