Using prediction 14e2a246-a11b-469c-ad0d-5502cbfd905a for map and profile fit
Ellipse and circular profile fits to the timings (chords) |

Auto-Fit Result: Size = 368 x 91 km a',b' = 184.0, 45.3 km X0,Y0 = 30.6, -29.9 km Mean diameter = 183 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. |
