keyword=hit patterns on R-armThe hit patterns on R-arm for T1 show an anomolous peak at
zero for Num PMT hits on S1, and also a peak at (-1,1) in the
S1-S2 hit pattern, where -1 means no hit. This is consistent
with what others saw, and does not exist on L-arm. After seeing
Marat's event printout, I wonder if the 2nd peak always occurs
accompanied by a large ADC amplitude; it might help to know.
As for the large angle T1's, it is normal. We do not use an MLU
since Dec 2000, the T1,T3 is a simple overlap of S1 and S2 planes.
