keyword=Comparison of 4272 and 4324Figures 1 and 2 show the focal plane and tracking distributions for runs 4272 (blue line) and 4324 (green). 4272 is with mis-matched septum and p=1.494 GeV/c. 4324 has matched septum and p=1.405 GeV/c.
As can be seen, the y-FP and phi-FP distributions are shifted wrt each other, as well as phi and y-tg. This is exactly what is expected when the septum is mis-matched with the HRS momentum. Clearly, the y-tg reconstruction is effected the most.
