Using prediction 181c5550-f5e5-11ee-4333-186b769fa938 for map and profile fit
Ellipse and circular profile fits to the timings (chords) |

|
Auto-Fit Result: X0,Y0 = 1012.9, 17.7 km Circular diameter = 31 km From 2 chords (VID) 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. |
