Demonstration of the effect of averaging over sub-configurations on the reconstruction yielding the best overlap values for the mantle and the void (Table 4). Left: reconstruction obtained in Case IV of signal configuration 92/1. The asteroid mantle is depicted by the green surfaces and the void by the blue ellipsoid. Right: enhanced regularity of reconstruction layer 1 was obtained with the averaged reconstruction corresponding to configuration 10/10 in Case IV, although the overlap between the void and the reconstruction is inferior to that of configuration 92/1.
