Central ray for 6.75 GeV protons in 20 T field, with beam tilted by 65 mrad in y-z plane at.

Report
Central ray for 6.75 GeV protons in 20 T field, with beam tilted by 65 mrad in y-z plane at the origin.
At the entrance and exit of the graphite target, z =  40 cm, the beam is off center from the target axis
by 4 mm in x, and ~ 0.1 mm in y
As noted in the past by Ole Hansen, it may be better to offset the target by ~ 2 mm with respect to
the proton beam to improve the muon yield.
