keyword=Gas Cerenkov Before and After CenteringYesterday with Jack's help we centered the gas Cerenkov. It was clear
from the run taken early Monday (2215) that the right side was seeing more
events than the left side. I found that the Cerenkov was off center by
about 2" yesterday. Figure 1 shows the off-center plot of the ADC spectra,
and Figure 2 shows a plot from run 2325 after the detector was centered.
The left and right sides look much more balanced now.
