Using prediction 2f9d38d0-ddb4-11f0-547e-0862bfe69af2 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 62 x 32 km a',b' = 30.9, 16.0 km X0,Y0 = 543.3, 33.6 km Mean diameter = 44 km From 5 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.
