\caption{The parameters used and the expected neutrino event rates
in KM3NeT after five years of observation for each SNR. The
visibility indicates the fraction of time when the source is below
the horizon to KM3NeT, and we take the visibility and the expected
atmospheric neutrino event rates for each source from Kappes et~al.
