Greetings G12'rs I have uploaded a preliminary plot of the beam energy vs cross section starting at higher beam energies since my start point of 2.2GeV previously seemed to be in question. I also changed the cross section units to microbarns. http://clasweb.jlab.org/rungroups/g12/wiki/index.php/Yield_Calculation#Wednesday_September_21.2C_2011 BR MK
