Query: Localization length index in a Chalker-Coddington model: a numerical
  study   We calculated numerically the localization length index $\nu$ for the
Chalker-Coddington model of the plateau-plateau transitions in the quantum Hall
effect. By taking into account finite size effects we have obtained $\nu =
2.593 \pm 0.0297$. The calculations were carried out by two different programs
that produced close results, each one within the error bars of the other. We
also checked the possibility of logarithmic corrections to finite size effects
and found, that they come with much larger error bars for $\nu$.
