Setup

In order to setup a python virtual environment with the corresponding dependencies, do the following:

1. pip install virtualenv
2. virtualenv myenv
3. source myenv/bin/activate
4. pip install -r requirements.txt

Afterwards you can use your virtual python environment in order to run the code. But before you do, you need to setup the properties.env. Inside of properties.env you will find different configuration variables which are used throughout the code in order to control the behavior of the code. Below you can find a table which summarizes what these environment variables do.

Environment Variable	Use-Case
LOWER_COSTHETAK_CUT	Controls the lower boundary of cos(theta_K)
UPPER_COSTHETAK_CUT	Controls the upper boundary of cos(theta_K)
SYS_PATH	We need one local package in order to make the code work, namely hep_analytics which you can also find in this repo, the interpreter needs to find that package, so set SYS_PATH to the relative path to hep_analytics
GEN_FILE	Path to the Generator File
MC_FILE	Path to the MC File
MC_PHSP_FILE	Path to the PHSP MC File
You are done!
