detectors, and an estimate of the rate of background events. We restrict attention to neutron star{black hole (NS-BH) binary systems, and we compare a search using non-spinning templates to one using templates that include spins aligned with the orbital angular momentum. To run the searches we implement the binary inspiral matched-lter computation in PyCBC, a new software toolkit for gravitational-wave data analysis. We nd that the inclusion of aligned-spin eects signicantly increases the astrophysical reach of the search. Considering astrophysical NS-BH systems with non-precessing black hole spins, for dimensionless spin components along the orbital angular momentum uniformly distributed in ( 1; 1), the sensitive volume of the search with aligned-spin templates is increased by 50% compared to the non-spinning search; for signals with aligned spins uniformly distributed in the range (0:7; 1), the increase in sensitive volume is a factor of 10.
