Using prediction 14eaa530-ddb0-11f0-547e-2758caeb57d5 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 60 x 9 km a',b' = 30.0, 4.6 km X0,Y0 = -279.8, 9.2 km Mean diameter = 23 km From 3 chords (CCD,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.
