GWTC-3: Gravitational-Wave Search Sensitivity Estimates for O3 Run

HDF injection summary files for search sensitivity estimates from the LIGO–Virgo–KAGRA Collaborations' third observing run (O3). The data product is associated with GWTC-3, the third Gravitational-Wave Transient Catalog, and includes separate files for the O3a and O3b sub-runs, as well as for subpopulations like binary neutron stars and binary black holes. It was created by the LIGO Scientific Collaboration.

Use Cases

• Estimating detection sensitivity for binary neutron star mergers based on the provided BNS subpopulation files.
• Modeling search completeness for binary black hole events using the BBH subpopulation data.
• Conducting population inference studies using the combined mixture model file spanning all mass ranges.
• Comparing detector performance between the O3a and O3b observing periods using the time-specified files.

Strengths

• Data is part of the official GWTC-3 release from the LIGO, Virgo, and KAGRA collaborations.
• Files are organized by specific subpopulations (BNS, NSBH, BBH, IMBH) and by observing period (O3a, O3b, full O3).
• Documentation is referenced, including a markdown file describing injected distributions and the HDF file format.

Limitations

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