Auto-Fit Result: Size = 355 x 330 km a',b' = 177.3, 165.1 km X0,Y0 = -3463.5, 15.4 km Mean diameter = 342 km From 8 chords (CCD,VID) 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. |
