JPL#96 : 01540cf0-ddb5-11f0-547e-6ab8df7f06f5 [db: observed]

Using prediction 01540cf0-ddb5-11f0-547e-6ab8df7f06f5 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: X0,Y0 = 3535.4, 21.6 km Circular diameter = 41 km From 2 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.
