Auto-Fit Result: Size = 65 x 61 km a',b' = 32.7, 30.4 km X0,Y0 = -3932.3, 23.8 km Mean diameter = 63 km From 4 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. |
