Interfacing with CLASS

The main power spectrum calculations performed in pyRSD require the linear matter transfer function. We provide an interface to the CLASS CMB Boltzmann code via the pyRSD.pygcl module.

The pyRSD.pygcl module is the General Cosmology Library, a swig-generated Python wrapper of a C++ library that provides useful cosmological functionality, including an interface to the CLASS code.
