We will fit a model composed of three long-lived (fundamental) modes, following [Siegel et al. (2023)](https://arxiv.org/abs/2307.11975). We will also use this as an example for loading open data directly from the Gravitational Wave Open Science Center (GWOSC) using [GWpy](http://gwpy.github.io)." ] }, { "cell_type": "markdown", "id": "c1adc8e9", "metadata": {}, "source": [ "
