For the cases \alpha_2 with U=2.25 and U=3.6 additional eigenvector gif 
files and data files for the system size N=9999, not shown 
in the paper, have been joined. 

Furthermore in the subfolder ALPHA1 additional gif files and data files of 
comparable system sizes N=265, 1633 and 10063 have been joined for the 
\alpha_1 case (these cases also not shown in the paper).
