Using prediction f19eb1a9-a34e-4101-a263-d87428b6da29 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 = 160 km From 5 chords (VID,VIS) 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. |
