One loop standard perturbation theory calculations

This repository is a supplement to arXiv:1907.13109  (Non-linear contributions to angular power spectra) and contains the Mathematica notebooks used to compute 1-loop corrections in cosmological standard perturbation theory.
The uploaded files are as follows:

1- P13.nb is a Mathematica notebook for computing P13 coefficients as explained in Appendix(A) of the paper.

2- P22.nb is a Mathematica notebook for computing P22 coefficients as explained in Appendix(A) of the paper.

3- pk_linear_CAMB_planck18_z0.0_neutrinomass0.dat is the linear power spectrum computed using CAMB with the parameters given in the paper.

4- P13_and_P22_coeffs.zip contains P13 and P22 coefficients computed with the given Mathematica notebooks.
