Auto-Fit Result: Size = 180 x 137 km a',b' = 89.9, 68.5 km X0,Y0 = 806.5, 60.2 km Mean diameter = 157 km From 6 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. |
