Observing regions of interest on Ganymede and Callisto with JUICE

We summarize the "segmentation" analysis that in the framework of the JUICE mission has been carried out for the dedicated orbital phase around Ganymede and for Callisto flybys, as far as the JANUS framing camera and the MAJIS imaging spectrometer are concerned. First we introduce an updated list of local-scale regions of interest so far identified for these two bodies. Then we identify the opportunities of observation of these regions by JANUS and MAJIS, both separately and simultaneously, so as to emphasize the possible complementarities deriving from a potential combination of the data of these two instruments.
