Harmonia is a Python package that combines clustering statistics decomposed in spherical and Cartesian Fourier bases for large-scale galaxy clustering likelihood analysis.

We recommend that you first install nbodykit by following these instructions.

After that, you can install Harmonia simply using pip:

pip install harmoniacosmo

Note that only here does the name "harmoniacosmo" appear because unfortunately on PyPI the project name "harmonia" has already been taken.

API documentation can be found at mikeswang.github.io/Harmonia. Tutorials (in the format of notebooks) will be gradually added in the future; for now, scripts in application/ may offer illustrative examples of how to use Harmonia.
