unequal-time power spectrum functions

unequalPy: A package for the unequal-time matter power spectrum

This package contains functions to obtain the unequal-time power spectrum at one-loop in standard perturbation theory an effective field theory. It also provides functions to reproduce the analysis in [1]:

• Approximations to the unequal-time matter power spectrum: geometric and the midpoint approximations.

• Weak lensing functions: filters and lensing efficiency.

• Tests using DES-Y1 data and cosmoSIS.

The full list of features can be found in the unequalPy Documentation.

Getting Started

unequalPy is distributed through PyPI. To install UnequalPy and its dependencies using pip:

$ pip install unequalpy

The unequalPy library can then be imported from python:

>>> import unequalpy
>>> help(unequalpy)

Examples: you can run some examples provided in our tests and analysis jupyter notebooks.
