Licence

BeAR is released under the GNU Public Licence (GPL) 3.0. That means, it can be freely copied, edited, and re-distributed. If the code is re-distributed it has to be released under at least a GPL 3.0 licence as well. The full licence of BeAR can be found in the repository (LICENSE file) or under https://www.gnu.org/licenses/gpl-3.0.html.

This user guide is released under the Creative Commons Licence (CC BY SA). Licensees may copy and distribute the work and make derivative works based on it only if they give the authors the credits by providing a reference to the original guide and the corresponding GitHub repository. Licensees may also distribute derivative works only under a license identical to (“not more restrictive than”) the license that governs the original work.

The BeAR repository also links to additional open-source codes:

• the equilibrium chemistry FastChem (https://github.com/newstrangeworlds/fastchem)

• the MultiNest nested-sampling code (https://github.com/farhanferoz/MultiNest)

• the C++ Boost library (https://github.com/boostorg/)

• the PyBind11 library (https://github.com/pybind/pybind11)

• the CDisort discrete ordinate radiative transfer (included in this repository)

FastChem and CDisort are released under the GPL 3.0 licence as well. MultiNest and Boost use their own open-source licences. PyBind11 is released under a BSD-style licence. The full licences of these codes can be found in the respective repositories. With the exception of CDisort, all codes are downloaded and compiled during the installation of BeAR and are, thus, not part of the BeAR repository.
