[G14_run] Vertex Distribution

[Reinhard Schumacher]

Hello Natalie,
     Thanks for the quick work.  The one-dimensional plots will be 
helpful to get a rough quantitative measure of how much material was in 
the targets.  It appears to me that the data already show the silver 
target was partially (perhaps half) full, while the present March target 
is closer to all full, similar to the test target.
