Contents:

fields     --> Sample fields stored in the original omega_y-phi form. 
               See the README.txt file for the file format.

statistics --> Standard average profiles in wall-units and energy balances.
               See the README.txt file of each directory 
               for further details.

spectra    --> 1D-2D energy and enstrophy spectra, and 1D-2D uv-cospectra
               as functions of streamwise and spanwise wavenumbers, and
               of wall-distance.
               See the README.txt file for the file format.
