Top: Azimuthal forward/backward correlation of the first moment of the
Et distributions, i.e. resulting directions of
sum(Et*cos(phi),Et*sin(phi)) in forward and backward pseudorapidity
windows.
Bottom: Impact parameter dependence of the correlation strength a1
compared to VENUS calculations using different amounts of sidewards
flow. (For explanation of the FLOW parameter see flow_6.ps.)
