Using prediction 62602db7-4b85-4705-ad2e-ba6963cee4bc for map and profile fit
Ellipse and circular profile fits to the timings (chords) |

Auto-Fit Result: X0,Y0 = 3502.0, -71.2 km Circular diameter = 13 km From 2 chords (VID,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. |
