py-SP(k) is a python package aimed at predicting the suppression of the total matter power spectrum due to baryonic physics as a function of the baryon fraction of haloes and redshift.

Requirements

The module requires the following:

• numpy
• scipy

Installation

The easiest way to install py-SP(k) is using pip:

pip install pyspk [--user]

The --user flag may be required if you do not have root privileges.

Usage

A simple example:

import pyspk as spk

z = 0.125
fb_a = 8.44e-05
fb_pow = 0.275
k, sup = spk.sup_model(SO=200, z=z, fb_a=fb_a, fb_pow=fb_pow, k_max=10)

A jupyter notebook with more examples can be found within this repository.
