- Methods:

   The code is mainly based on the formalism described in `Carullo et al., arXiv:1902.07527 <https://arxiv.org/abs/1902.07527>`_.
   For signals extending below a pure ringdown emission, it uses the truncated formulation of `Isi et al., arXiv:1905.00869 <https://arxiv.org/abs/1905.00869>`_ (see also `their longer follow-up, arXiv:2107.05609 <https://arxiv.org/abs/2107.05609>`_).   
   Additional details on the methodology can be found in the `GWTC-2 Testing GR LVK catalog, arXiv:2010.14529 <https://arxiv.org/abs/2010.14529>`_ and `GWTC-3 Testing GR LVK catalog, arXiv:2112.06861 <https://arxiv.org/abs/2112.06861>`_.

   A pedagogical discussion of models usage and systematic uncertainties can be found in `Gennari et al., arXiv:2312.12515 <https://arxiv.org/abs/2312.12515>`_.
