JPL#54 : 59e07000-ddb7-11f0-547e-940172ff8756 [db: observed]

Using prediction 59e07000-ddb7-11f0-547e-940172ff8756 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: Ellipse profile fit was not successful. Trying circular fit. Circular profile fit was not successful ... 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.
