<font face="Helvetica, Arial, sans-serif">Hi All,<br>
<br>
I look at "quasi-exclusive" single pi0 production and comparing
full target to empty target yields of pi0s<br>
with the "GlueX" trigger.<br>
The plot shows in the top half the pi0 yields in red the scaled
empty target and in the bottom half the pi0s<br>
angle (theta) in the lab. The scale factor was deduced by the
number of PS triggers for the runs used in<br>
this analysis and evaluated to 0.35.<br>
<br>
Runs used for full: 100989, 100963, 100952, 100951<br>
Runs used for empty: 100842, 100841, 100836, 100835, 100834<br>
<br>
cheers,<br>
Beni<br>
