Catalog Analyzer: A library for Spherical Fourier Bessel (SFB) Decomposition

CatAna is a C++ library and Python package to perform fast spherical Fourier Bessel transformation (Fourier transformation in spherical coordinates) on discrete, point-like datasets.

The code is hosted on GitHub. Please contact the author if you have any questions, find bugs or have ideas to improve CatAna.
