Due to several factors, the amplitude of these gravitational-wave signals, and hence their distances, can be usually measured better than for neutron star binaries. We will show that, depending on the value and orientation of the black hole spin, neutron star black hole mergers can provide a competitive measurement of the Hubble-Lemaître constant.
