[Clascomment] OPT-IN: The Beam-Target E asymmetry for vec gamma vec n -> pi- p in the Nâ resonance region

[Dr. A.M. Sandorfi]

Hi Volker,

Thanks for the comments.
The invariant mass is total rest energy of the system (apart from c^2).
While I don't think that will confuse any potential reader, I have now
replaced almost all references of energy with $W$ or invariant mass. (I kept
energy in only a few places to let the English flow more smoothly by not
repeating the same word over and over.)
My plan is to upload the data to the CLAS data base just before submission.

Andy
