For this setup you will need to install miniconda on the machine you are working and do the following procedure:
1.`conda env create -f requirements.yaml`
2. Check with `conda activate angularanalysis` if the environment is working
3. Check out the following page in order to install the analysis-tool package: `https://github.com/jonas-eschle/analysis-tools`
4. Check out the following page in order to install the angular-analysis B->K*ll package: `https://gitlab.cern.ch/LHCb-RD/ewp-bd2ksteeangular-legacy/-/tree/master/b2kstll`
Afterwards you can use your conda 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.
|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|
If you want to see how to set the environment variables, have a look at `properties.env`. Also, I have run the code on the LHCbA1 machine but it should make no difference where you run the code.
