Convergence of orbital parameters for Linus, moon of (22) Kalliope, derived from our genetic algorithm using a Keplerian model Genoid-Kepler. One solution with an orbital period of 3.595712 days is evident. The other orbital elements and their 3-sigma errors are listed in Table 1. The 3-sigma error bar corresponds to the mean precision of astrometry provided by the adaptive optic observations.
