Table 7.

Emission estimates at 135.6 nm and 630 nm, in Rayleigh, induced by electron impact for auroral regions at Ganymede (Case 2) for an invariable neutral atmospheric model. The contribution (in %) of the photo-induced emission, estimated at 25 R (see Table 6) compared to the total emission at 630 nm, is also indicated.
