Intensities and durations of Ganymede–Jupiter radio emissions compared to Io–Jupiter and non-Io ones. Panel a: distributions of intensities (in dB above the Galactic background) of Io–Jupiter, non-Io, and Ganymede–Jupiter radio emission events, normalized to an Earth–Jupiter distance of 5.2 AU (in black). A rescaled distribution of Ganymede–Jupiter radio emissions matching Io and non-Io ones is displayed in red. Panel b: durations of Ganymede–Jupiter radio emissions compared to Io–Jupiter and non-Io ones. Normalized distributions of durations of Io–Jupiter, non-Io, and Ganymede–Jupiter radio emission events, corrected from the variable Earth–Jupiter distance, are displayed in black. Rescaled distributions of Ganymede–Jupiter radio emissions matching Io–Jupiter and non-Io ones are displayed in colour.
