keyword=scaler checks
For the run Kalyan analyzed he said that T6++ and T2-+ disagreed
between Left and bigbite. Here I check T6 using the scalers in Podd
and find that indeed these two banks (Left, BB) track well but
for the T6++ combination the Left counts more by a constant ratio
of 1.41 which happens to be sqrt(2), probably a coincidence.
Making the signals wider was a good idea. The scalers have a limited
bandwidth and I know, for example, 10 nsec is a disaster, while
100 nsec is fine, so somewhere in between. At this point the problem
might be individual weaknesses of channels, something I've never
seen before, but bumping up the width (just to see what happens)
may be a good thing to try.
BTW, you can see the target flipping pretty nicely (fig 2)
