Python packages to conduct studies of the Extragalactic Background Light (EBL).
For the simplest use, i.e. reading in EBL model files and calculating the gamma-ray attenuation from them, you'll need a running version of python 2.7 and newest versions of the following packages:
- numpy
- scipy
- matplotlib
Some extra packages are also required if you want to perform non-standard calculations included in the directories tools/, ppa/, ebl/
Download the package, add the path of the repository to your python home variable, e.g. by typing (or including in your .bashrc file):
export PYTHONPATH="$PYTHONPATH:/path/to/repo:/some/other/path:"
To use EBL model files, you have to set the EBL_FILE_PATH environment variable, e.g., by typing
export EBL_FILE_PATH=/path/to/repro/ebl/ebl_model_files
The EBL model files are included in the ebl path. Check the installation by running
python example.py
The script is heavily commented to explain its use.
