Using prediction 81572870-ddb4-11f0-547e-2b97bef7d65b for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 194 x 51 km a',b' = 96.9, 25.3 km X0,Y0 = 973.9, 22.3 km Mean diameter = 99 km From 6 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.
