Auto-Fit Result: Size = 157 x 66 km a',b' = 78.5, 32.8 km X0,Y0 = -805.9, -10.9 km Mean diameter = 101 km From 5 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. |
