ANALDIR

Need to know:

Were Trigger 2 events filtered in the lr-files in the directory:
/net/data/9/Analysis/data
to prevent particles in the neutral particle sector from having tracks?
The Veto on raw hits in the WC used to cut out more than 95% of the
trigger 2 events and now when I analyze trigger 2 events, and then use
a charge veto, I'm only cutting out approximately 20%... This doesn't
seem right because I could've swore that there were much more events
in the trigger 2 yield.

For run 11251: lr-11251.root

root [1] lr->Draw("qwl","qwl==-1&&trig==2")
(Int_t)2588
root [2] lr->Draw("qwl","qwl==-1&&trig==2&&hwr<13")
(Int_t)2093
