Currently **263** events across 12 catalogs (GWTC-1-confident, GWTC-1-marginal, GWTC-2.1-auxiliary, GWTC-2.1-confident, GWTC-2.1-marginal, GWTC-3-confident, GWTC-3-marginal, GWTC-4.0, IAS-O3a, Initial_LIGO_Virgo, O3_IMBH_marginal, O4_Discovery_Papers). ## Dataset description Each row represents one gravitational wave event (merger of compact objects such as black holes and/or neutron stars). Parameters include component masses, distance, spins, signal-to-noise ratio, and astrophysical probability. For each measured parameter, lower and upper uncertainty bounds are provided where available. ## Schema | Column | Type | Description | |--------|------|-------------| | `name` | string | Event name (e.g. GW150914, GW230529) | | `gps` | float | GPS time of the event | | `catalog` | string | Source catalog short name | | `run` | string | Observing run (O1/O2, O3a, O3b, O4a, ...) | | `mass_1` | float | Primary source mass (solar masses) | | `mass_1_lower/upper` | float | 90% credible interval bounds | | `mass_2` | float | Secondary source mass (solar masses) | | `mass_2_lower/upper` | float | 90% credible interval bounds | | `chirp_mass` | float | Chirp mass (solar masses) | | `luminosity_distance` | float | Luminosity distance (Mpc) | | `redshift` | float | Cosmological redshift | | `chi_eff` | float | Effective inspiral spin parameter | | `network_snr` | float | Network matched-filter SNR | | `p_astro` | float | Probability of astrophysical origin | | `far` | float | False alarm rate (Hz) | | `final_mass` | float | Remnant mass (solar masses) | | `final_spin` | float | Remnant dimensionless spin | All parameters with uncertainties also have `_lower` and `_upper` columns. ## Quick stats -
