[Halld-cpp] full/empty target in single pi0 production

Hi All,

I look at "quasi-exclusive" single pi0 production and comparing full 
target to empty target yields of pi0s
with the "GlueX" trigger.
The plot shows in the top half the pi0 yields in red the scaled empty 
target and in the bottom half the pi0s
angle (theta) in the lab. The scale factor was deduced by the number of 
PS triggers for the runs used in
this analysis and evaluated to 0.35.

Runs used for full: 100989, 100963, 100952, 100951
Runs used for empty: 100842, 100841, 100836, 100835, 100834

cheers,
Beni
