Using prediction b492dcd0-ddb8-11f0-547e-e3c9fbf9a897 for map and profile fit

Ellipse and circular profile fits to the timings (chords)

Auto-Fit Result: X0,Y0 = -1265.4, 41.6 km Circular diameter = 44 km From 2 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.
