Transform angular power spectra and correlation functions (transformcl)

This is a minimal Python package for transformations between angular power spectra and correlation functions. It is currently limited to the zero spin case.

The package can be installed using pip:

pip install transformcl

Then import the cltocorr() and corrtocl() functions from the package:

from transformcl import cltocorr, corrtocl

Current functionality covers the absolutely minimal use case. Please open an issue on GitHub if you would like to see anything added.

Reference/API

cltocorr	transform angular power spectrum to correlation function
corrtocl	transform angular correlation function to power spectrum
theta	compute angles for DLT function values
cltovar	compute variance from angular power spectrum
