GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the Second Part of t

HDF injection summary files provide sensitivity estimates for gravitational-wave searches conducted by the LIGO, Virgo, and KAGRA collaborations. The data spans the first three observing runs (O1, O2, O3) and covers binary neutron star, neutron star–black hole, binary black hole, and intermediate mass black hole subpopulations. This material is part of the GWTC-3 data release from the LIGO Scientific Collaboration.

Use Cases

• Modeling detection probability for binary neutron star mergers based on the provided BNS subpopulation files.
• Comparing semi-analytic sensitivity estimates (O1, O2) with real search results (O3) for binary black hole events.
• Estimating the optimal network signal-to-noise ratio thresholds for historical observing runs.
• Analyzing search sensitivity across a mixture of compact binary coalescence mass ranges.

Strengths

• Data is associated with the authoritative third Gravitational-Wave Transient Catalog (GWTC-3).
• Covers three distinct observing runs (O1, O2, O3) from the LIGO–Virgo–KAGRA network.
• Provides separate files for four distinct astrophysical subpopulations (BNS, NSBH, BBH, IMBH).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
