Using prediction ecc079be-bbe8-49be-bed5-2c7513dbb203 for map and profile fit
Ellipse and circular profile fits to the timings (chords) |
---|
|
Auto-Fit Result: Circular profile fit was not successful ... 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. |
