The box dimensions and atomic positions were obtained by perturbing a 64-atom simple hexagonal supercell (4x4x4 1-atom unit cells) constructed using a lattice constant of a=2.639 Angstroms with c/a=0.94 (equilibrium LDA-DFT values quoted in H. Balamane, T. Halicioglu, and W. Tiller, Phys. Rev. B 46, 2250 (1992).). Each atomic position was perturbed in a random direction with a magnitude of displacement no greater than 0.5 Angstroms. Each of the three supercell vectors was also perturbed randomly with a magnitude of displacement no greater than 0.5 Angstroms."
