JPL#73 : 9d6b4f40-ddb5-11f0-547e-8da9d7fd1e9a [db: observed]

Using prediction 9d6b4f40-ddb5-11f0-547e-8da9d7fd1e9a for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Size = 31 x 12 km a',b' = 15.7, 5.8 km X0,Y0 = 1060.5, 45.8 km Mean diameter = 19 km From 5 chords (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.
