Public Member Functions inherited from STU
double	computeThValue ()
	Empty constructor.
double	F (const double m02, const double m12) const
	Function \(F(m02,m12)\) used for THDM. Remember that this function is defined for THDM while for SUSY we have a multiplicative factor 2.

	A get method to get the model.
const std::vector< std::string >	getParametersForObservable ()
	A get method to get the parameters for the specific observable.
void	setBinMax (double max)
	A set method to set the maximum value of the bin.

	Constructor.
	ThObservable (const ThObservable &orig)
	The copy constructor.
virtual	~ThObservable ()
	The default destructor.
