As an accompaniment to "GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs", this page contains the associated data release of posterior (and prior) samples detailing the inference on the compact binary coalescence observations presented in the above publication.

Documentation for the content of the sample release, together with examples of how to access and create plots of the sample release content are available in the attached 'GWTC-1_sample_release.ipynb' notebook.

For the O1 events (GW150914, GW151012, GW151226), the samples provided below supersede the samples given in the O1 parameter estimation samples release.

NOTE: Prior to 11 June 2019, the PE samples released on this page for a fraction of events suffered from an issue with the application of priors for spin parameters and a slight normalization issue. We have verified that none of the results are meaningfully impacted, but we recommend that any results using the previously released samples be reanalyzed using the corrected samples, which were posted to this page on 11 June 2019.
