plima

PLIMA is the Python Library for Intrinsic alignment Models and Amplitudes.

PLIMA provides simple tools for working with intrinsic alignment models in cosmology. It includes model level amplitude functions and CCL backend helpers for building intrinsic alignment inputs used in weak lensing analyses.

Models

PLIMA currently includes:

• LA
• NLA
• TATT
• halo model IA

Installation

You can easily install plima via pip:

pip install plima

For development, clone the repository and install it in editable mode:

git clone https://github.com/cosmology-kit/plima.git
cd plima
pip install -e ".[dev]"
