  Wall turbulence has a sublayer where one-point statistics, e.g., the mean
velocity and the variances of some velocity fluctuations, vary logarithmically
with the distance from the wall. This logarithmic scaling is found here for
two-point statistics or specifically two-point cumulants of those fluctuations
by means of experiments in a wind tunnel. As for corresponding statistics of
the rate of the energy dissipation, the scaling is found to be not logarithmic.
We reproduce these scaling laws with some mathematics and also with a model of
energy-containing eddies that are attached to the wall.
