Jet Energy Flow

Nothing much here except the code used to make the W mass plot from the SNOWMASS 2001: JET ENERGY FLOW PROJECT. The plot was made for the hadronic final state in boson fusion events ( qq -> qqWW ) at the LHC. The hadronically decaying W's are really boosted so both quarks are close together and the only thing that has to be plotted to make this plot is the JEF measurement of "jet mass". Also, there was no detector simulation !

Though I'm pretty sure the plot itself is correct, the code comes with no warranty whatsoever.

This wortk was also presented here by Steve Ellis and here by me.

jef.cxx, jef.hh and an example of how to use them (which won't compile without a bunch of other crap I haven't put here, sorry. And anyway it is all such bad code that you won't want to. Even I'm better at c++ than this now).
