Top left: asymmetry rate of trigger T3
bottom left: trigger rate of T3
Top middle: asymmetry rate of trigger T4
bottom middle: trigger rate of T4
top right: accumulated charge asymmetry from BCMu3
bottom right: gate time difference between helicity +1 and -1.
As mentioned in entry 65639. The false charge asymmetry from left arm is due to the asymmetry in gate time, it is clearly shown here.

Right arm data from run 20754
top left: rate from BCM u3
bottom left: aymmetry rate from BCM u3
top middle: trigger rate ---T1
bottom middle: trigger rate asymmetry for T1
top right: accumulated charge asymmetry from BCM u3
bottom right: gate time difference helicity +1 and -1.
(Compared with left arm, the charge asymmetry from right arm is better)
