Veto Results on pi0 Analysis with 3 clusters

I analyzed 10 files of run 5242 which was a pi0 production run with the carbon target. I selected events with 3 clusters only and reconstructed the pi0 from the permutations of 2 clusters. Next, I flagged the veto status for each cluster in the permutation. Comparisons are shown below with a few veto/cluster combinations.

Number of clusters per event

Here is a legend of the different colors:

• Black - No veto required.
• Red - Veto says both clusters are photons (1).
• Green - Veto says both clusters are charged (2).
• Blue - Veto says 1 cluster is charged, and the other cluster is a photon (3).
