Notes. The initial orbit elements are taken from Revs 273, 274, 278, 280, and 284 of the Cassini Grand Finale mission from SPICE. The periapsides are at distances of about 3000 km. The orbital eccentricity is close to 0.9, which is highly eccentric. The inclination angles are about 57° at middle latitude.
