Summary

• We compared 5.3 and 6.1 data using Stntuple high
  pt muon dataset
• Looked at the identification variables needed to
  ID muon
• Found agreement
• we do not expect change in the value of the ID
  efficiency
• Need to understand behavior of CMIO forward muons

Subsample of events

• Events with one tight trigger muon (CMUP or CMX)
  and one additional muon which can only be a CMIO
