Auto-Fit Result: Size = 26 x 11 km a',b' = 13.0, 5.4 km X0,Y0 = 2412.5, 14.5 km Mean diameter = 17 km From 6 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. |
