Abstract

This data release underpinning the paper "Assessing the imprint of eccentricity in GW signatures using two independent waveform models" contains parameter estimation products for compact binary merger events analysed using the RIFT inference engine with eccentric, aligned spin waveforms: SEOBNRv5EHM and TEOBResumS-Dali. This release contains analyses for the 162 compact binary merger events from O3–O4a utilized in the paper, as well as 11 additional O1-O2 events included in subsequent population-level analyses. The provided compressed file contains two directories: posterior samples and corresponding likelihood evaluations. Each file follows this naming convention: {GW_name}_{waveform}, denoting the gravitational-wave event name and waveform model used in the analysis (SEOBNRv5EHM or TEOBResumSDALI). Posterior samples The posterior samples directory contains posterior samples (*.h5) for 173 events spanning O1-O4a. These files were prepared with PESummary and include the configuration files containing prior and analysis settings. The files can be read using the following keys, depending on the waveform analysis: rift-SEOBNRv5EHM rift-TEOBResumSDALI Likelihood evaluations The likelihood evaluations directory contains the intrinsic log-likelihood evaluations/ILE output (*.net) for each analysis. Each line corresponds to one evaluation point.
