The literature_samples folder contains the q-xeff samples from the literature.
The results folder contains the deep followup results for the various case studies.
The run_configs folder contains the configuration files analyses.

To reproduce the values from the Vajpeyi et al (2022) paper tables, run the following commands:

pip install -r requirements.txt
python print_odds.py

This will print the following:

External Data

This work utilised some external data. The data is described below:

1. q-xeff Posteriors
* The q-xeff samples labelled as 'Mateu' are obtained from Mateu-Lucena et al (2022)
* The q-xeff samples labelled as 'Nitz' are obtained from Nitz et al (2021)
* The q-xeff samples labelled as 'Chia' are obtained from the authors of Chia et al (2022), via email correspondence

2. Gravitational Wave Strain Data
* The raw strain data from the LIGO Hanford and Livingston detectors are obtained from GWOSC. The get_data.py script in the run_configs folder demonstrates how the data is downloaded.

3. Gravitational Wave PSD Data
* The PSDs for the GW150914 and GW151226 analyses are obtained from the LIGO dcc
