Fig. 1From: Distribution of water-group ion cyclotron waves in Saturn’s magnetosphere a Cassini orbit projection in the X–Y equatorial plane, in a Saturn-centered coordinate system. b Cassini orbit projection in the cylindrical R–Z plane. The positive X-axis is pointing toward noon time. The orbit curves are in red when the wave frequencies are near to the local water-group ion gyrofrequenciesBack to article page
