keyword=target endcaps can be seenFor the run number 1407 where we have pi ^- and electrons in the right arm when I look at the preshower corrected adc sum there are two peaks for the place where we get pi^- events as shown below. But when we cut on the target endcaps these peaks go away, suggesting that we should always cut on the y_tg to look at the physics, since the end caps can give you all kinds of junk.
