keyword=Charge Asymmetry runs 3521 and 3462Figure 1 shows the charge asymmetry for run # 3462. This plot has
a cut to remove beam trips. However there is still one bin near
-9000 ppm. Figure 2 shows the charge asymmetry for the u10 and d10
BCMs versus time and the rates in u10 and d10 versus time (bottom
left and right plots). The -9000 ppm bin correlates to the point at
80 on the y-axis in the bottom plots. Hence this bin is related to
the beam trip and should be thrown out.
I think this confirms that the problem with runs 3444 to 3463 is not
related to a large charge asymmetry, though it could be a sympton of
the problem.
