PEANUTS is a software for the automatic computation of solar neutrino flux and its propagation within Earth. It is designed to be fast, so that it can be efficiently used in global scans, and flexible, so it allows the input of custom solar models, Earth density profiles, etc.

PEANUTS runs successfully on any system with a Python 3 environment and the following mandatory packages: numpy, numba, os, copy, time, math, cmath, mpmath, scipy, pyinterval, decimal and pandas. Optional packages for I/O operations are pyyaml and pyslha.
A detailed explanation of how to run PEANUTS and all available options can be found in the reference above. Here are listed the various running modes of PEANUTS without explanation.
The simple mode of PEANUTS runs directly on the command line and can be used with
run_prob_sun.py [options] <energy> <fraction> [<th12> <th13> <th23> <delta> <dm21> <dm3l>]
to compute the probability on the Surface of the Sun, and
run_prob_earh.py [options] -f/-m <state> <energy> <eta> <depth> [<th12> <th13> <th23> <delta> <dm21> <dm3l>]
to compute the probability at a location below Earth's crust.
The expert mode of PEANUTS can be run with
run_peanuts.py -f <yaml_file>
where the given YAML file determines the specific computation to perform.
