## Class Description

     TLimitDataSource

     This class serves as interface to feed data into the TLimit routines

TLimitDataSource()

     Default constructor

TLimitDataSource(TH1D * s, TH1D * b, TH1D * d)

     Another constructor, directly adds one channel
     with signal, background and data given as input.

void AddChannel(TH1D * s, TH1D * b, TH1D * d)

     Adds a channel with signal, background and data given as input.

void AddChannel(TH1D * s, TH1D * b, TH1D * d, TH1D * es, TH1D * eb, TObjArray * names)

     Adds a channel with signal, background and data given as input.
     In addition, error sources are defined.
     TH1D are here used for convenience: each bin has to be seen as
     an error source (relative).
     names is an array of strings containing the names of the sources.
     Sources with the same name are correlated.

void SetOwner(bool swtch)

     Gives to the TLimitDataSource the ownership of the various objects
     given as input.
     Objects are then deleted by the TLimitDataSource destructor.

             TObjArray* GetErrorOnBackground()

                TClass* IsA() const
                   void ShowMembers(TMemberInspector& insp, char* parent)
