... At current sensitivity levels, the GW detectors are limited to relatively nearby sources. For instance, a stellar-mass black hole / neutron star binary inspiral can be detected out to a maximum distance of ~50 Mpc. Therefore, we target galaxies within 50 Mpc when selecting coordinates for follow-up ...
