[en] We describe the effort to characterize gravitational-wave searches and detector sensitivity to different types of compact binary coalescences during the LIGO-Virgo-KAGRA Collaborations’ fourth observing run. We discuss the design requirements and example use cases for this data product, constructed from >4.33 × 108 injections during O4a alone. We also identify subtle effects with high confidence, like diurnal duty cycles within detectors. This paper accompanies a public data release of the curated injection set, and the Appendixes give detailed examples of how to use the publicly available data.
