The original version of this Article contained errors in Eqs. (3), (4), (5), and (6) which were incorrectly written as:

$${\it{\Gamma }} = \left( {3.2 - 8.5} \right) \times 10^{ - 3} \times \left( {0.0116{\mathrm{/Mpc}}^3} \right)\left( {N_{\mathrm{c}}{\mathrm{/}}200} \right)\,{\mathrm{yr}}^{ - 1}\,{\mathrm{Gpc}}^{ - 1}\,{\mathrm{for}}\,{\mathrm{NSSTBH}},$$
(3)
$$ \left( {1.7 - 2.5} \right) \times 10^{ - 1} \times \left( {0.0116{\mathrm{/Mpc}}^3} \right)\left( {N_{\mathrm{c}}{\mathrm{/}}200} \right)\,{\mathrm{yr}}^{ - 1}\,{\mathrm{Gpc}}^{ - 1}\,{\mathrm{for}}\,{\mathrm{BHSTNS}},$$
(4)

and

$$ {\it{\Gamma }}_{{\mathrm{NC}}} = \left( {0.9 - 1.7} \right) \times 10^{ - 4} \times \left( {0.0116{\mathrm{/Mpc}}^3} \right){\mathrm{yr}}^{ - 1}\,{\mathrm{Gpc}}^{ - 1}\,{\mathrm{for}}\,{\mathrm{NSSTBH}},$$
(5)
$$ \left( {1.0 - 1.5} \right) \times 10^{ - 2} \times \left( {0.0116{\mathrm{/Mpc}}^3} \right)\,{\mathrm{yr}}^{ - 1}\,{\mathrm{Gpc}}^{ - 1}\,{\mathrm{for}}\,{\mathrm{NSSTBH}},$$
(6)

The correct version of these equations is:

$${{\Gamma }}_{{\mathrm{GC}}} = \left( {3.2 - 8.5} \right) \times 10^{ - 3} \times \left( {{\uprho}_{\mathrm{MWEG}}/0.0116\,{\mathrm{Mpc}}^{ - 3}} \right)\left( {N_{\mathrm{c}}/200} \right)\,{\mathrm{yr}}^{ - 1}\,{\mathrm{Gpc}}^{ - 3}\,{\mathrm{for}}\,{\mathrm{NSSTBH}},$$
(3)
$$ \left( {1.7 - 2.5} \right) \times 10^{ - 1} \times \left( {{\uprho }}{_{{\mathrm{MWEG}}}/0.0116\,{\mathrm{Mpc}}^{ - 3}} \right)\left( {N_{\mathrm{c}}/200} \right)\,{\mathrm{yr}}^{ - 1}\,{\mathrm{Gpc}}^{ - 3}\,{\mathrm{for}}\,{\mathrm{BHSTNS}},$$
(4)
$$ {\it{\Gamma }}_{{\mathrm{NC}}} = \left( {0.9 - 1.7} \right) \times 10^{ - 4} \times \left( {{\uprho }}{_{{\mathrm{MWEG}}}/0.0116\,{\mathrm{Mpc}}^{ - 3}} \right){\mathrm{yr}}^{ - 1}\,{\mathrm{Gpc}}^{ - 3}\,{\mathrm{for}}\,{\mathrm{NSSTBH}},$$
(5)
$$ \left( {1.0 - 1.5} \right) \times 10^{ - 2} \times \left( {{\uprho }}{_{{\mathrm{MWEG}}}/0.0116\,{\mathrm{Mpc}}^{ - 3}} \right)\,{\mathrm{yr}}^{ - 1}\,{\mathrm{Gpc}}^{ - 3}\,{\mathrm{for}}\,{\mathrm{BHSTNS}}.$$
