1. Execute:
root -b -q upperlimit.C

... to produce a nice upper limit plot based on the "simple channel" workspace taken from :
analysis/simplechannel/README

2. This produces two files:
The plot: upperlimit_cls_poi_example_Asym_CLs_grid_ts3.root.eps
The hypothesis test results that can be used to recreate the plot:
example_Asym_CLs_grid_ts3.root

3. Run the macro with:

int calculatorType=2;  // frequentist
int npoints=6; 

and again:

root -l upperlimit.C

to see the actual test statistic distributions used to determine the upper limit!
