title: Data release for paper "First eccentric inspiral-merger-ringdown analysis of neutron star-black hole mergers"

description: This data release for the paper "First eccentric inspiral-merger-ringdown analysis of neutron star-black hole mergers" contains posterior samples for the 3 binary neutron star-black hole merger events analysed, obtained from public GWOSC data with the bilby Bayesian inference package (via parallel_bilby), dynesty nested sampler and a set of waveform models (IMRPhenomTHM, IMRPhenomTEHM).

The provided compressed file contains 11 hdf5 bilby posterior files, which can be read easily using bilby standard tools (concretely bilby.read_in_result(file), see bilby docs for details). If you make use of these samples, please cite both this data release and the paper.

For all cases, fref is set to 20Hz, the coordinates are EOB, and the samplers used are the default by parallel_bilby, except for one case which uses random walk (rwalk). Most of the runs are obtained using IMRPhenomTEHM, allowing for two different priors used for the eccentricity parameter: either "Uni" for uniform, or "LogUni" for log-uniform priors. Additionally, each event includes at least one quasi-circular run using the IMRPhenomTHM (THM) model.

Default settings correspond to an initial frequency for the likelihood integration of 20Hz; a duration of 32 seconds for GW200105, 64s for GW200115, and 128s for GW230529; and a starting frequency for the waveform of 17Hz. In the case of GW200105, extra runs were performed varying all these quantities, indicated in the name on the "nondefaultdetails" placeholder.

Concretely:



64s indicates a duration of 64s of data.

33band indicates that all (l,m)<= (3,3) are in band at 20Hz, so the waveform starts at 13.2Hz.

25HzL1 indicates that the likelihood integration starts at 25Hz for LIGO Livingston.
