GWTC-4.0 Cumulative Search Sensitivity Estimates

Cumulative LIGO-Virgo-KAGRA (LVK) search sensitivity estimates are provided for quasi-circular compact binary coalescences (CBCs) throughout the advanced detector era (O1 - O4a). These are represented as tabular data containing the parameters of simulated CBCs along with the significance assigned to each simulated signal by a number of searches. Details of individual files can be found in gwtc-4_o1234a_sensitivity-estimates.md and Essick et al (2025) arXiv:2508.10638 Additional information about the O4-only injections is available here: zenodo:16740117
