Occurrence probability of the emission not induced by Io nor by Ganymede, separated by their sources, distributed as a function of the CML and Europa’s orbital phase (left). Distribution of the occurrence probability integrated over the entire CML range (0°–360°) (center). Distribution of the occurrence probability integrated over the CML range in which enhanced occurrence is observed (right). The horizontal white lines (in the plots on the left) and the vertical black lines (in the other plots) delimit the phase intervals associated with the Eu-DAM emission detected by Louis et al. (2017). The dashed lines delimit the CML ranges of probability integration shown in the plots on the right.
