the grid is dynamically added in the 3d program i am using .
Ceres's orbit is calculated using the JPL orbit data and Dawn's orbit is also calculated using it's orbital data the same data that the research scientists are using the naif kernels. As to the map. The map posted is 0 long to 360 long ( 180 in the center ) a grid could be added ? but not really needed this very EARLY map is very low resolution 1024x512 pixels and the poles ARE MISSING. In comparison the published Vesta map is 48 ppd ( 17,280 X 8,641 ) pixels . |
