In the published article, an error was introduced when we computed S/NΔ to compare waveforms of binary neutron stars and neutron star–black hole binaries, as shown in Figure 2 therein. After correcting the error, the signal-to-noise ratio (S/N) is reduced by roughly a factor of 2. The corrected Figure 2 is shown here, including an updated caption. In addition, in the main text, the sentence "We assume that the binary is at a distance of 100 Mpc" should be corrected to "We assume that the binary is at a distance of 50 Mpc," and the sentence "Within most of the parameter regime we consider here, S/NΔ is bounded below ∼1
2 should be refined as, "Within most of the parameter regime we consider here, S/NΔ is bounded below 1."
Figure 2. S/N computed using Equation (8) and assuming a binary at a distance of 50 Mpc. The mass of NS 1 is assumed to be 1.35 M⊙. This S/N is a function of the radius of the NS 1 and the binary mass ratio. As the S/N is inversely proportional to distance, a 1.35 M⊙+1.35 M⊙ (with NS radius ∼12 km) binary event in the Virgo cluster should have an S/NΔ around 2.
