schNell is a very lightweight python module that can be used to compute basic map-level noise properties for generic networks of gravitational wave interferometers. This includes primarily the noise power spectrum "N_ell", but also other things, such as antenna patterns, overlap functions, inverse variance maps etc.

You can install schnell simply by typing

pip install schnell [--user]

(use --user if you don't have admin privileges on your machine). Or for development versions you can download the repository with git and install from there using python setup.py install [--user].

Documentation can be found on readthedocs.

This example notebook on github also showcases the main functionalities of the module.

Check out the following videos showing the scanning patterns of different GW networks.

• LIGO instantaneous sensitivity
• LIGO cumulative sensitivity
• LISA instantaneous sensitivity
