Description File
\( \ell=2 \) Regge-Wheeler RBC kernel for \(r_b=30M \) and AWE kernels from \(r_1=30M \) to \(r_2=2M(1\times 10^{-15})\). Experiment documented in Section IIC of Fast evaluation of asymptotic waveforms from gravitational perturbations. The 19 pole extraction table has same pole locations as the 19 pole RBC table, but the 26 pole extraction table is more accurate. BFL_SectionIIC_DecayTails.tar.gz
MATLAB codes which perform simulation in Section IIC of Fast evaluation of asymptotic waveforms from gravitational perturbations, among others (see README). LateTimeTailsMATLAB.tar.gz
RBC kernels for spin-2 Regge-Wheeler potential (tolerance \(\varepsilon = 10^{-15}\) with \(2\leq \ell \leq 64\) and \(r_b = 30M, 60M, 120M, 240M, 480M\)). Note, Heun is used here since the Regge-Wheeler equation is an incarnation of the singly confluent Heun equation. [format] TablesHeunRBC.tar.gz
