Using prediction 1fd19a2c-7409-4eca-b456-9d2c6ad5cca5 for map and profile fit
Ellipse and circular profile fits to the timings (chords) |

Auto-Fit Result: Size = 97 x 36 km a',b' = 48.5, 18.0 km X0,Y0 = 3459.4, 17.1 km Mean diameter = 59 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. |
