$\mathtt{qnm}$ 是一个开源 Python 包,用于计算 Kerr 拟正模频率、角分离常数和球-球混合系数。 $\mathtt{qnm}$ 软件包包括一个 Leaver 求解器,采用 Cook-Zalutskiy 谱方法来处理角扇区,以及一个避免重复计算的缓存机制。我们提供了低 $\ell、m、n$ 模式的大型缓存,可以通过单个函数调用来下载和安装这些模式,并进行插值以在新的自旋值下为根抛光提供良好的初始猜测。
$\mathtt{qnm}$ is an open-source Python package for computing the Kerr quasinormal mode frequencies, angular separation constants, and spherical-spheroidal mixing coefficients. The $\mathtt{qnm}$ package includes a Leaver solver with the Cook-Zalutskiy spectral approach to the angular sector, and a caching mechanism to avoid repeating calculations. We provide a large cache of low $\ell, m, n$ modes, which can be downloaded and installed with a single function call, and interpolated to provide good initial guess for root-polishing at new values of spin.
