22. We note that the shape of the lines connecting the ν = 6 and the ν = 4 regions in Fig. 1 [see "necks" in Fig. 1(a) and the crossings in Figs. 1(b) and 1(c)] depends crucially on the DOS used (e.g., Lorentzian or Gaussian) and the broadening of the Landau levels. This will be discussed in detail elsewhere (Ferreira, Freire and Egues, in preparation).
