MathWAP contains Mathematica notebooks that compute the Fourier power spectrum and bispectrum, including contributions (up to second order) from wide-separation (WS) and relatativistic (GR) efects as well as primoridal non-Gaussianity (PNG). Outputs are stored from Mathematica in .json files in mathematica_expr. The read_mathematica notebook can be used to convert from Mathematica to Python formatting for use by CosmoWAP (ascl:2507.020).
