On the other hand, in the ellipsoidal system, where every direction has its own character, the speci cation of a coordinate system is based on a reference ellipsoid which establishes the variations in angular dependence. The reference ellipsoid is given by the equation x 2 1 a 2 1 + x 2 2 a 2 2 + x 2 3 a 2 3 = 1, 0 < a 3 ... WebThe modelling suggests that the ratio of \photometric" ellipsoid axes is 10:2:1, whereas the ratio of the axes of asteroid body is 4:2:1. Therefore, Duende shape greatly diﬁers from ellipsoid and, possibly, its albedo is non-homogeneous. The axis of rotation of the asteroid has moved by 52– between these two sets of observations.
