keyword=charge asymmetry in run 1287Looked at the spectrometer event asymetry from run 1287.
for trigger 1-5 only, plotted the assigned helicity (helxj3).
There are 475687 hel=+1, and 472208 hel=-1, so the asymmetry
is 3670 +/- 1027 ppm. From the plot, clearly there's more +1 than -1.
Given the small charge asymmetry to start with, I conclude that
we at least got the sign right.
