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

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.
