# Requirements
* [`CMasher`](https://cmasher.readthedocs.io/)
* gfortran (or equivalent f95 compiler, but make sure to edit src/like/Makefile)

# Running the code
The heavy lifting of the likelihood analysis is done in a short fortran program (src/like/like.f95), which can be executed via python. To start, compile the fortran likelihood code by doing
```
make -C src/like
```
Then to run one of the python scripts do e.g.
```
cd src
python runNuFloor_SI.py Xe
```
using one of the following scrips:
* [`src/runNuFloor_SI.py`](https://github.com/cajohare/NeutrinoFog/tree/main/src/runNuFloor_SI.py) - SI limits
* [`src/runNuFloor_SDp.py`](https://github.com/cajohare/NeutrinoFog/tree/main/src/runNuFloor_SDp.py) - SD (proton) limits
* [`src/runNuFloor_SDn.py`](https://github.com/cajohare/NeutrinoFog/tree/main/src/runNuFloor_SDn.py) - SD (neutron) limits
* [`src/runNuFloor_NuFluxUncertainties.py`](https://github.com/cajohare/NeutrinoFog/tree/main/src/runNuFloor_NuFluxUncertainties.py) - To test the effect of neutrino flux uncertainties

Each takes about 30 minutes per target on my machine, but the resolutions can be lowered to generate them faster.
