Using prediction 3c659643-08b9-4a81-9464-2bb7f3a7e6da 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 diameter = 85 km From 3 chords (CCD) 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. |
