Fig. 2: Each subfigure shows the angle-averaged SNR for binaries fixed at different redshifts.

For each point, we take an average of 1000 events, which are sampled with priors shown in Table 2. The blank region with no points in the lower subfigures represents the binary systems with angle-averaged SNR < 10. Packages GWFish³⁶ and astropy⁵⁴ are used to produce the figure.
