Using prediction 4ce03de9-4abc-4a15-84f8-bb90f89efec9 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. |
