Query: Corrections to Scaling in the Integer Quantum Hall Effect   Finite size corrections to scaling laws in the centers of Landau levels are
studied systematically by numerical calculations. The corrections can account
for the apparent non-universality of the localization length exponent $\nu{}$.
In the second lowest Landau level the irrelevant scaling index is
$y_{\mathrm{irr}}=-0.38\pm0.04$. At the center of the lowest Landau level an
additional periodic potential is found to be irrelevant with the same scaling
index. These results suggest that the localization length exponent $\nu$ is
universal with respect to Landau level index and an additional periodic
potential.
