Auto-Fit Result: Size = 120 x 88 km a',b' = 60.2, 44.1 km X0,Y0 = 623.8, 17.9 km Mean diameter = 103 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. |
