## 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
