Which Seyfert galaxies will the KM3NeT neutrino detector see?

IceCube detected neutrinos coming from Seyfert galaxies, but mostly caught Northern Hemisphere sources. The KM3NeT telescope, deployed in the Mediterranean, can search the Southern sky for the same signal. Assuming neutrino output scales with X-ray brightness, four galaxies—NGC 1068, NGC 4151, NGC 4945, and Circinus—should be bright enough to detect, though thick dust around three of them complicates the prediction.
