be found in our preprint [[arXiv:2406.10337]](https://arxiv.org/abs/2406.10337).\nMore details to follow after the peer review process.\n\n### Statistical analysis

superrad\n-  _Optional_: Python packages emcee, jupyterlab, matplotlib, tqdm\n\n### Step-by-step guide\n\n1. Install the dependencies into your Python environment via `python -m pip install iminuit numba numpy qnm scipy superrad`\n2. Clone this repo via `git clone https://github.com/sebhoof/bhsr`\n\n\n## How to get started\nWe include the Jupyter notebook [examples.ipynb](examples.ipynb) to demonstrate a few of the capabilities of our code.\n\n\n## How to cite\n\nEven if you wish to *only* cite our code, we still ask you to cite [[arXiv:2406.10337]](https://arxiv.org/abs/2406.10337) and to include a link to this Github repo.\nSadly, code citations are still not widely recognised.\n\nWe (re-)distribute posterior samples from various BH data sets.\nIf you make use of the data included in the `data/` folder, the following works should be cited:\n\n| Black hole name | Samples | Reference(s) |\n| :--- | :--- | :--- |\n| IRAS 09149-6206 | _M_ | [[arXiv:1705.02345]](https://arxiv.org/abs/1705.02345), [[arXiv:2009.08463]](https://arxiv.org/abs/2009.08463) |\n| | _a*_ | [[arXiv:2009.10734]](https://arxiv.org/abs/2009.08463) |\n| M33 X-7 | _(M,a*)_ | [[arXiv:0803.1834]](https://arxiv.org/abs/0803.1834) |\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsebhoof%2Fbhsr","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsebhoof%2Fbhsr","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsebhoof%2Fbhsr/lists"}
