Using prediction 154eeaf2-e8a6-4fa5-9a81-998ab5c18204 for map and profile fit
Ellipse and circular profile fits to the timings (chords) |

|
Auto-Fit Result: X0,Y0 = -544.5, 7.3 km Circular diameter = 74 km From 2 chords (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. |
