我们已经更新了轨道的小内土星卫星使用额外的卡西尼成像观测到2007年3月。与先前公布的数值相比，Pan和Daphnis的偏心率和倾角出现了统计上的显著变化，但其他卫星的估计轨道只有很小的变化。由于2006年初观察到的近距离接触，我们也提高了对雅努斯和厄庇墨透的质量的认识。
We have updated the orbits of the small inner Saturnian satellites using additional Cassini imaging observations through 2007 March. Statistically significant changes from previously published values appear in the eccentricities and inclinations of Pan and Daphnis, but only small changes have been found in the estimated orbits of the other satellites. We have also improved our knowledge of the masses of Janus and Epimetheus as a result of their close encounter observed in early 2006.
