We do see the very high pT muons in MC
Difference in MET cuts is 4
Leading Jet Cut is a relative 1 hit

L1 Conf Bad Jets
Note 3.2 is not the same as 3.4!!!
Switch from L1 coverage from 2.4 to 3.2 occurred
with v11
(Trigger DB Web Pages) Run lt 178512
Trigger list v10 and below (90pb-1)
Brigittes web page
top_analyze doesnt take this into account.. Like
having an hlt2.4 cut
munbb loose 150/2.3
munbqb loose 200/6.3

Misc

• Noise Jets
• There are 2.4 in MC that have noise jets
• There is no L1Conf in MC
• MET
• Top_analyzes fully corrected MET has all bad
  jets taken out
• Both ones that fail L1Conf and those that dont
  pass ID cuts
• Im pretty sure we are cutting on this verison of
  MET.
• Eliminate the event?
• How do we calculate the efficiency hit?
• Muons
• Our gt1 muon rejection apply a DRgt0.5 as well?
• What happened to muon horn elimination?
• All eta cuts up to now have been physics eta.
• We should probably get some plots of various
  things vs luminosity/time.
• of Ws strikes me as a good one.
• Luminosity Calculations is going to be tedious
• Be glad we are staying away from prescaled
  triggers.
