For the stochastic (and some FCI calculations for expected values as well as some Hilbert space estimations), the HANDE QMC code was used, https://github.com/hande-qmc/hande (or, possibly for older versions, https://doi.org/10.5281/zenodo.1158670). See output file git hashes for version.

Note that some python files were cleaned up for upload here (e.g. unused/irrelevant lines removed, etc). For code in folder det-proj, see its own licence and comments to what has been changed for upload.

Various python packages were used, such as NumPy (https://numpy.org/), Matplotlib (https://matplotlib.org/), Pandas (https://pandas.pydata.org/) and SciPy (https://www.scipy.org/). The plotting scripts should work with these versions: Python 2.7.11, NumPy 1.13.0, Matplotlib 2.0.2, Pandas 0.17.1, SciPy 0.19.1.
