Document type:

P - Publications

Abstract:

As an accompaniment to "GW190425: Observation of a Compact Binary Coalescence with Total Mass ~3.4 Msun", this page contains the associated data release of:

• An hdf5 file containing:
  • posterior (and prior) samples detailing the inference on the compact binary coalescence observations presented in the above publication (which includes three parameterized waveform families, each with low-spin and high-spin priors);
  • power spectral densities (PSDs) of the L1 and V1 detector noise around this event;
  • calibration uncertainty envelopes around this event;
  • the configuration file associated with the LALInference parameter estimation runs.
• A python notebook 'GW190425_posterior_samples.ipynb' and associated html file which documents the content of the sample release, together with examples of how to access and create plots of the sample release content.
• Strain data around this event are available at the GW Open Science Center (GWOSC), at gw-openscience.org.
• Skymaps are available at GraceDB.ligo.org.
