JPL#114 : 9c4804f0-ddb5-11f0-547e-46273672984f [db: observed]

Using prediction 9c4804f0-ddb5-11f0-547e-46273672984f for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 124 x 99 km a',b' = 61.9, 49.7 km X0,Y0 = -806.3, 20.4 km Mean diameter = 111 km From 6 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.
