Figure 24: Gravitational-wave spectrum for representative models with the expected detection limits of the first LIGO [11], the advanced LIGO [277], Large-scale Cryogenic Gravitational wave Telescope (LCGT) [219], and Fabry-Perot type DECIGO [215, 278]. It is noted that is the characteristic gravitational wave strain defined in [220]. The supernova is assumed to be located at the distance of 10 kpc. This figure is taken from [216].
