Each .dat file contains the ground-state average occupation per site of a 9x2 square helicity lattice  with four left and four right enantiomers for chosen tunneling and interaction parameters.
The parameters are given in each .dat file.
The x-axis of the lattice is periodic, while the y-axis is open.
The occupations are obtained by a direct diagonalization of the Hamiltonian.
Each number in the .dat file represents the average occupation in one site. The occupation can be easily plotted with an imshow plot or similar.
