Waves from Coalescing
The stochastic binary background produced by nearby galaxies from Tully's
catalog at the frequency 
Hz is shown in Figure 49 in terms
of average strain metric amplitude per square degree in a given direction
(l,b) on the sky:
where the sum is calculated over all sources in the given square degree
of the sky; we assumed 
.
The lines of constant 
on the sky (so-called isograwes) are plotted in Figure 50.
As we expected (see Section 15.9),
only the closest and most massive galaxies (such as SMC, LMC, M31, M82,
M87) can be clearly discerned by a GW detector with angular resolution
of 1
against the galactic
binary GW stochastic background.
