Data release: Measuring orbital eccentricity with SEOBNRv6EHM

Posterior samples from the parameter-estimation analyses presented in: L. Pompili, A. Gamboa, and A. Buonanno, Eccentric and unbound compact binaries in the LIGO--Virgo--KAGRA catalog: parameter estimation and waveform systematics with SEOBNRv6EHM (2026): arXiv:2605.28716 Contents The data release contains 26 HDF5 result files, one per gravitational-wave event analyzed with the SEOBNRv6EHM waveform model. The files contain the results of eccentric aligned-spin parameter-estimation analyses for events spanning the O1–O4 LIGO–Virgo–KAGRA observing runs, including binary black hole, neutron-star–black-hole, and binary neutron star mergers. Each file is a Bilby result object stored in HDF5 format. It can be loaded with: import bilbyresult = bilby.read_in_result("samples/GW150914_v6EHM_result.hdf5")posterior = result.posterior The notebook load_results.ipynb shows how to load and plot the samples.
