Using prediction 19be9ea0-ddb4-11f0-547e-e7fcfeafb3fe for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 154 x 145 km a',b' = 77.0, 72.5 km X0,Y0 = -944.2, 34.1 km Mean diameter = 149 km From 11 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.
