keyword=Cuts after modifyingHere are the cuts I used for calculation:run#1767
1. DL.evtypebits -- events number 438735
2. L.prl1.asum_p:L.prl2.asum_p {((DL.evtypebits&1<<3)==1<<3)} -- events
number 407641
3. L.prl1.asum_p:L.prl2.asum_p
{((DL.evtypebits&1<<3)==1<<3)&&L.cer.asum_p>400} -- events number 359354
4. L.prl1.asum_p:L.prl2.asum_p
{((DL.evtypebits&1<<3)==1<<3)&&L.cer.asum_p>400&&abs(L.tr.vz)<0.15} -- events
number 201464
5. L.prl1.asum_p:L.prl2.asum_p
{((DL.evtypebits&1<<3)==1<<3)&&L.cer.asum_p>400&&abs(L.tr.vz)<0.15&&L.prl1.asum_p>1000&&L.prl2.asum_p>1000}
-- events number 183119
6. L.prl1.asum_p:L.prl2.asum_p
{((DL.evtypebits&1<<3)==1<<3)&&L.cer.asum_p>400&&abs(L.tr.vz)<0.15&&L.prl1.asum_p>1000&&L.prl2.asum_p>1000&&L.tr.n==1}
-- events number 180465
Efficiency = 180465/438735 ~ 41.13 %
