Just a couple of numbers I'm having trouble finding. Does anyone know what a typical energy for a nuetrino ejected from the sun is? Any number on a guess-timate of what the density of nuetrinos is in deep space? Also, same two questions for electron nuetrinos and Tau nuetrinos. A 1 Gev Nuetrino, would the gamma for this nuetrino be 4.5(10^8)?
