Constructor & Destructor Documentation

hitfit::Fit_Results::Fit_Results	(	int	max_len,
		int	n_lists
	)

Constructor, make n_list of lists, each of maximum length max_len.

Parameters

max_len	The maximum length of each list.
n_lists	The number of lists.

Member Function Documentation

const Fit_Result_Vec & hitfit::Fit_Results::operator[]

(

std::vector< Fit_Result_Vec >::size_type

i

)

const

Access the i-th list.

Parameters

i	The index of the list.

References _v, and i.

{
  assert (i < _v.size());
  return _v[i];
}

void hitfit::Fit_Results::push	(	double	chisq,
		const Lepjets_Event &	ev,
		const Column_Vector &	pullx,
		const Column_Vector &	pully,
		double	umwhad,
		double	utmass,
		double	mt,
		double	sigmt,
		const std::vector< int > &	list_flags
	)

Add a new fit result.

Parameters

chisq	The fit .
ev	The event kinematics.
pullx	The pull quantities for the well-measured variables.
pully	The pull quantities for the poorly-measured variables.
umwhad	The hadronic W mass before fit.
utmass	The top quark mass before the fit.
mt	The top quark mass after the fit.
sigmt	The top quark mass uncertainty after the fit.
list_flags	Vector indicating to which lists the result should be added. This vector should have a same length as the internal object _v.
