Jet Flavour Tagging Howto

Line: 115 to 115
  Once the AIDA Plots processors are run via Marlin, a text file PurityEfficiencyOutput.txt and a RAIDA root file are produced. We customised the MakePurityVsEfficiencyRootPlot.C macro and ran it to use the RAIDA file as input to produce the purity vs. efficiency plots:
Changed:

<
root -l bbPurityVsEfficiencyRootPlotGla.C
>
>
root -l MakePurityVsEfficiencyRootPlotGla.C
  Here's a plot of our flavour tagging purity vs. efficiencies (using cca. 25k events):

The cut values and corresponding purity and efficiencies are tabulated in the file PurityEfficiencyOutput.txt. From these values, one can calculate and optimum b-cut.
>
>
The cut values and corresponding purity and efficiencies are tabulated in the file PurityEfficiencyOutput.txt. We used another Root macro to plot these values and determine the optimum b-cut.

For b-tagging, we've compared the plot produced by MakePurityVsEfficiencyRootPlotGla.C and graphs drawn with the data tabulated in PurityEfficiencyOutput.txt, for 1, 2, 3 or any number of vertices:
