As we look ahead to LIGO, Virgo and KAGRA (LVK)ís next observational run (O4) and future gravitational wave observatories such as Cosmic Explorer, understanding the sensitivity of a detector network to compact binary coalescences (CBCs) is important for estimating the merger rate density. The parameter space of CBCs is composed of many parameters, which are used to characterize the binary systems. In this work, we explore how the network sensitivity (space-time sensitive hypervolume) changes according to changes in the CBC population parameter space. Using Monte Carlo simulations, we calculate the averaged space-time sensitive hypervolume for different parameter configurations, marginalizing over subsets of the parameter space so that we can compare them.
