Using prediction 67f90797-873e-423d-a7a7-a55634b01390 for map and profile fit
Ellipse and circular profile fits to the timings (chords) |

Auto-Fit Result: Size = 9 x 2 km a',b' = 4.7, 1.2 km X0,Y0 = -83.1, 16.5 km Mean diameter = 5 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. |
