This analysis targets binary black hole systems with LIGO and Virgo. The larger component mass ranges from 0.5 to 10 solar masses while the smaller component mass ranges from 0.5 to 1 solar mass. This ensures that each binary searched for has at least one sub-solar mass component. Spin magnitudes are limited to a maximum of 0.3 . Offline searches of SSM will use a broader bank that extends down to 0.2 solar masses and spin magnitudes of 0.9 .
