pyrfu 2.3.22

Python Space Physics (RymdFysik) Utilities

pyRFU

The Python package pyrfu is a software based on the IRFU-MATLAB library to work with space data, particularly the Magnetospheric MultiScale (MMS) mission.

It is distributed under the open-source MIT license.

Full documentation can be found here

Instalation

The package pyrfu has been tested only for Mac OS.

Using PyPi

pyrfu is available for pip.

pip install pyrfu

From sources

The sources are located on GitHub:

https://github.com/louis-richard/irfu-python

1. Clone the GitHub repo:

Open a terminal and write the below command to clone in your PC the pyrfu repo:

git clone https://github.com/louis-richard/irfu-python.git
cd irfu-python

2. Create a virtual env

pyrfu needs a significant number of dependencies. The easiest way to get everything installed is to use a virtual environment.

• Anaconda

You can create a virtual environment and install all the dependencies using conda with the following commands:

pip install conda
conda create -n pyrfu
source activate pyrfu

• Virtual Env

Virtualenv can also be used:

pip install virtualenv
virtualenv pyrfu
source pyrfu/bin/activate

3. Install the package via the commands:

python setup.py install

5) (Optional) Generate the docs: install the extra dependencies of doc and run the setup.py file:

pip install pyrfu
python setup.py build_sphinx

Once installed, the doc can be generated with:

cd doc
make html

Dependencies

The required dependencies are:

• cdflib >=0.3.20

• matplotlib >=3.2.1

• numba >=0.52.0

• numpy >=1.18.1

• pandas >=1.0.3

• Sphinx >=3.0.3

• scipy >=1.4.1

• setuptools >=47.3.1

• xarray >=0.15.0

Testing dependencies are:

• pytest >= 2.8

Extra testing dependencies:

• coverage >= 4.4

• pylint >= 1.6.0

Usage

To import generic space plasma physics functions

from pyrfu import pyrf

To import functions specific to MMS mission

from pyrfu import mms

To import plotting functions

from pyrfu import plot as pltrf

Configuration

Default configuration settings for MMS data (i.e data path) are stored in pyrfu/mms/config.json and can be changed at anytime using mms.db_init(local_path_dir).
