We trained this model on waveform data generated from point particle black hole perturbation theory (ppBHPT) with mass ratios varying from $3 \\leq q \\leq 1000$ and spins from $-0.8 \\leq \\chi_1 \\leq 0.8$. The waveforms are $13,500 \\ m_1$ long and include all spin-weighted spherical harmonic modes up to $\\ell = 4$ except the $(4,1)$ and $m = 0$ modes.
