Good Electron Cuts

The following cuts were applied to get an estimate of the number of good events per run in the left and right HRS:

Plots of these cuts can be seen here

1. Number of tracks = 1

  • L.tr.n==1
  • R.tr.n==1


2. Y-Target Tracking Variable

  • abs(L.tr.tg_y)<0.05
  • abs(R.tr.tg_y)<0.05


3. Number of Clusters in each VDC = 1

  • L.vdc.u1.nclust==1
  • R.vdc.u1.nclust==1


4. Cut on Golden Track dp

  • abs(L.gold.dp)<0.05
  • abs(R.gold.dp)<0.05


5. Cut on Golden Track theta

  • abs(L.gold.th)<0.05
  • abs(R.gold.th)<0.05


6. Cut on Golden Track phi

  • abs(L.gold.ph+0.03287)<0.05
  • abs(R.gold.ph-0.02709)<0.05


7. Cut on Lead Glass Detectors

  • (L.prl1.asum_p+L.prl2.asum_p)<2100&&(L.prl1.asum_p+L.prl2.asum_p)>1100
  • (R.sh.asum_p+R.ps.asum_p)<4500&&(R.sh.asum_p+R.ps.asum_p)>3000


8. Cut on Cherenkov Sum

  • L.cer.asum_p>250
  • R.cer.asum_p>250
