Detailed Description

The functions of this class deal with the initial random fluctuations of the scalar singlets. As described in the documentation, they consist in a sum of left-moving and right-moving waves in momentum space, whose amplitudes follow a Gaussian random distribution with variance given by and external power spectrum function.
