The repository is an expansion of the KCAP module which can be found here. To use the code in this repository, simply copy the files in the utils folder into the kcap/utils folder.

KCAP-nonLimber implements a new methodology to project 3D power spectra to 2D angular power spectra within the nonLimber module (Reischke et al. in prep.). This is achieved using the Levin method Levin 1994 and the code is available here.

Firstly, we have to install the nonLimber, a.k.a. levinpower, module:

git clone https://github.com/rreischke/nonLimber_matter_shells.git
cd nonLimber_matter_shells
pip install .

Then, we clone the KCAP repository:

git clone https://github.com/KiDS-WL/kcap.git
cd kcap/utils

Next, we copy all the files in the utils folder of this respository into the kcap/utils folder.

Then, we proceed with the installation of the KCAP module as outlined here. Note that the modules can also be copied into kcap after installation.
