 +As muons propagate through a cylindrical volume they begin creating neutrons and eventually the flux through the cylindrical area comes to constant.  This means in the first small percentage of the cylinder the flux is increasing and after that one can reliably extract the flux.  Below we plot the integrated 
 +flux (over the whole 10m sensitive cylinder) as a function of energy.
