==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 [http://hallaweb.jlab.org/halog/log/html/1112_archive/111219140307.html 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
