Reproducibility

The aim of this repository is to allow other users to reproduce the results shown in the paper and to enable them to easily get started with BNS parameter estimation with Jim. Therefore, we mention explicitly which versions of ripple, flowMC and Jim were used for the runs mentioned in this work. Below, we provide links to the repositories' version at the time of writing. We also provide a Zenodo release, which can be found here with ZIP files containing all three packages, as well as the version of this repository at the time of releasing the arXiv submission

Overview of this repository

We provide a quick overview of the contents of this repository.

RB

This directory contains the output files for the relative binning with Bilby runs mentioned in Table IV.

ROQ

This directory contains the output files for the ROQ with Bilby runs mentioned in Table IV.

ROQ-build

An attempt at constructing our own ROQ bases for the estimate of Appendix C. Eventually, we used the estimates provided by Soichiro Morisaki for Appendix C, as we find this source to be more trustworthy.

Data

A few data files used in the postprocessing scripts or injection runs.

Figures

Final figures used in the paper.

Injections

Directory storing all the scripts related to the simulated events, as well as the outdir directories of all runs. The produced posterior samples are too large to be stored on Github and can be shared upon request.

Postprocessing

A few scripts used to create the plots for the paper.

real_events

All scripts used in the analysis of the real events, GW170817 and GW190245, and the respective outdirs. The produced posterior samples are too large to be stored on Github and can be shared upon request.

Datafiles for the real events are too large to be stored on Github and can be found on the respective GWOSC websites. If more information is needed, please raise an issue on this Github.
