Please note that the models are in planetocentric coordinate system, with Z axis passing through north pole. Actual rotational axis may differ from planetocentric poles, especially for small irregular bodies.
Surface Textures
Textures are simple cylindrical projections with prime meridian at the middle, provided at the highest resolution available.
