Installation instructions

1. Basic install

pip install fwl-zephyrus

2. Developper install with code sources

git clone git@github.com:FormingWorlds/ZEPHYRUS.git
cd ZEPHYRUS
pip install -e .

3. Download input data The fwl-mors python package is used to compute the XUV stellar incoming flux on the planet, which most escape models rely on. This package requires a set of stellar evolution data, stored in the OSF repository. To download the data follow the following steps.
   • Set the environment variable FWL_DATA to define where the data files will be stored
     • export FWL_DATA=...
     • This can be done permanently by entering this line into you ~/.profile file.
   • Run the following command to download all evolution track data
     • mors download all

In the examples folder you can find python scripts showing typical usecases/workflows of escape computation with Zephyrus.
