Query: On the analytical approximation to the GLAP evolution at small x and
  moderate Q^2   Comparing the numerically evaluated solution to the leading order GLAP
equations with its analytical small-x approximation we have found that in the
domain covered by a large fraction of the HERA data the analytic approximation
has to be augmented by the formally non-leading term which has been usually
neglected. The corrected formula fits the data much better and provides a
natural explanation of some of the deviations from the $\sigma$ scaling
observed in the HERA kinematical range.
