class TFeldmanCousins: public TObject

 TFeldmanCousins

 class to calculate the CL upper limit using
 the Feldman-Cousins method as described in PRD V57 #7, p3873-3889

 The default confidence interval calvculated using this method is 90%
 This is set either by having a default the constructor, or using the
 appropriate fraction when instantiating an object of this class (e.g. 0.9)

 The simple extension to a gaussian resolution function bounded at zero
 has not been addressed as yet -> `time is of the essence' as they write
 on the wall of the maze in that classic game ...

    VARIABLES THAT CAN BE ALTERED

 => depending on your desired precision: The intial values of fMuMin,
 fMuMax, fMuStep and fNMax are those used in the PRD:
   fMuMin = 0.0
   fMuMax = 50.0
   fMuStep= 0.005
 but there is total flexibility in changing this should you desire.


 see example of use in $ROOTSYS/tutorials/math/FeldmanCousins.C

 see note about: "Should I use TRolke, TFeldmanCousins, TLimit?"
