Query: Multifractality of wavefunctions at the quantum Hall transition
  revisited   We investigate numerically the statistics of wavefunction amplitudes
$\psi({\bf r})$ at the integer quantum Hall transition. It is demonstrated that
in the limit of a large system size the distribution function of $|\psi|^2$ is
log-normal, so that the multifractal spectrum $f(\alpha)$ is exactly parabolic.
Our findings lend strong support to a recent conjecture for a critical theory
of the quantum Hall transition.
