Auto-Fit Result: Size = 216 x 103 km a',b' = 107.8, 51.7 km X0,Y0 = -1621.6, 20.2 km Mean diameter = 149 km From 9 chords (VID,VIS,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. |
