Hello,

Among other things, I'm making some plots for the white paper. I thought 
it would be nice to have the rapidity systematic of our pi, K, and p data 
in one figure. I produced such a plot, which shows dN/dy, mean Mt and mean 
Et.

I also made a quick estimation of the Bjorken energy density at mid-rap, 
given the mean Mt of each particle type (I've applied a factor of 1.5 for 
pions (pi0), 2 for kaons (K0s) and 2 for p and pbars, rough neutron 
estimation). I end up with epsilon = 4.95 GeV/fm3, not bad :)
