(color online) Occupied probabilities at sites of states in the four bands drifting into the zero energy in ZW₂-(6, 6) with N = 40. The integers refer to the site indices. (a) At 1-8 sites, (b) at 9-16 sites, (c) at 17-24 sites, (d) at 25-32 sites, and (e) at 33-40 sites. (f) In one premitive cell two edge sites 13 and 33 are denoted by big red balls expressing the probability 100%, and the four sites 9, 20, 29, and 40 are denoted by small red balls expressing 50%.
