Auto-Fit Result: Size = 97 x 51 km a',b' = 48.4, 25.4 km X0,Y0 = -1976.7, 30.0 km Mean diameter = 70 km From 3 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. |
