Auto-Fit Result: Size = 213 x 31 km a',b' = 106.7, 15.7 km X0,Y0 = -49.8, 12.7 km Mean diameter = 82 km From 3 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. |
