2. Default-LVL2 rates
Monika Wielers pointed us to AOD->ntuple example:
Works in , needs modifications for earlier versions
So we moved to Will need the AOD’s for dijet and Higgs
In the meantime, Francesca Sarri pointed us to her own ntuples, which have only a fraction of the trigger information
These variables seem sufficient for a manual implementation of the LVL1/LVL2/EF requirements.
Coding the ‘LVL2-FTK’ requirements in progress, but not working quite yet.
For the next meeting we plan to:
Transport our tracking req. code to the new ntuple environment, and
get signal and background AOD’s and run athena to get official-style ntuples. Larger in size but also more complete.

3. Very preliminary results
Dijet samples:
J sample (dijet pT range 8-17 GeV) : evts.
J sample (dijet pT range GeV) : evts.
J sample (dijet pT range GeV) : 6000 evts.
J sample (dijet pT range GeV) : 9630 evts.
Francesca does not have the dijet trigger rates in her talk, but rather points to a T&P talk by Eric Torrence:
Comparison to Eric’s values for single tau15i trigger shows 10-20% smaller L1/L2/EF rates:
