Ups, one more thing;
I saw that you have implemented TASS 1.7 for the Saturnian system; the orbital theory that acounts for the perturbations over Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion and Iapetus. Is there some solution for the rest of the moons of Saturn?
I think is important we can see for example the orbital exchange between Janus and Epimetheus. A very interesting phenomenon
that occurs every 4 years. Seen from Epimetheus how the 200 km sized Janus aproaches and then leaves swaping orbits between them it's a dream. In SE for now you just see them in opposite sides of Saturn, never coming close, never swaping orbits
