Gravitational wave amplitudes (blue) and (red) due to anisotropic mass flow and neutrino emission as a function of time for models W15-4 (left), L15-3 (middle), and N20-3 (right), respectively. The solid curves show the amplitudes for an observer located above the north pole (α = β = 0; see Fig. 10) of the source, while the other curves give the amplitudes at the equator (α = 0, β = π/2).
