Kernel positions of Uranus (5 × 5, in blue) and its moons (3 × 3, in black) shown on the Uranus subtracted product of OBSID 1342211117+18. Overlapping kernel elements (Uranus and Oberon on this given example here) caused redundancy in the fit of these kernel elements. Rotational symmetries were introduced into the kernels to eliminate this issue. The flux scale of the image is the same as in Fig. 4.
