1. Use Z->µµ + Jets Events
2. Selection:
   1. Muon: pt_1 see base selection for each year, pt_2 > 15 GeV
   2. Tau see base selection
   3. Z Mass Window: 70 < mZ < 110,
3. Fake rate Tight / (VLoose && !Tight), per decay mode

Same selection as for JetFakes ?

The Tau ID SF is measured by fitting the ZTT MC yield to data. It is measured binned in the inclusively or binned in the pT or the reconstructed decay mode of the tau lepton. The binning of the measurement is as follows:

• pt: [20,25,30,35,40,50,70,200]
• dm(MVA): [0,1,10]
• dm(DeepTau): [0,1,10,11]

To run the measurement invoke

bash TauIDSF_measurement/measure_TauIDSF.sh $ERA mt

from the top level directory of the sm-htt-analysis repository. This produces the necessary shapes for the inclusive and binned measurements and creates the datacards, workspace and performs the fit for the inclusive or one of the binned measurements specified inside the file. Additionally it produces prefit and postfit shapes and creates plots of these shapes.
