Galileo mission wave power statistics: a Average chorus intensity in each bin (ΔRJ = 0.5, ΔMLT = 0.5 h) for the equatorial region from 27 June 1996 until 5 November 2002, excluding encounters with the moons. b Same as a but for encounters with Europa (~9.4 RJ) and Ganymede (~15 RJ), positive x is toward the Sun (noon MLT), axes are in the magnetic equatorial plane. c Scatter plot of wave power as a function of the distance from Jupiter. Blue dots show Galileo encounters with Europa. Red dots show encounters with Ganymede. Diamond points are median values during encounters. Green line shows median values of the wave power excluding encounters. The error bars are absolute mean deviation. Median wave power during the encounters for Ganymede and Europa significantly exceeds the median values at corresponding distances from Jupiter
