Member Function Documentation

double TElectronMCShifterTool::getShiftDelta	(	double	eT,
		double	eta,
		ElePIDNames::Var	var
	)			[inline]

Get the shift amount.

Returns only the shift amount. This is the number in the Shifts table that is added to the variable to obtain the shifted result.

Parameters:

	eT	The eT value of the electron.
	eta	The eta value of the electron.
	var	enum member corresponding to the variable. Type is ElePIDNames::Var

Returns:

The shift value for the current electron/variable.

getShiftDeltaByBin()

double TElectronMCShifterTool::getShiftDeltaByBin	(	int	eT,
		int	eta,
		ElePIDNames::Var	var
	)			[inline]

Get the shift value from bin numbers.

Parameters:

	eT	The eT bin number [0-5].
	eta	The eta bin number [0-8].
	var	enum member corresponding to the variable. Type is ElePIDNames::Var

Returns:

The shift value for the current electron/variable.

void TElectronMCShifterTool::shiftAll	(	float	eT,
		float	eta,
		float &	rhad1,
		float &	rhad,
		float &	reta,
		float &	rphi,
		float &	weta2,
		float &	f1,
		float &	f3,
		float &	fside,
		float &	ws3,
		float &	wstot,
		float &	eratio,
		float &	e277,
		float &	DeltaE,
		float &	deltaeta1,
		float &	deltaphiRescaled
	)

shift all variables as references.

Takes in references to all of the variable values and modifies them directly. This is so it can be used in the xAOD wrapper class along with the photon tool.

Parameters:

	eT	The eT value of the electron.
	eta	The eta value of the electron.

Returns:

None

double TElectronMCShifterTool::shiftVar	(	double	eT,
		double	eta,
		ElePIDNames::Var	var,
		double	val
	)

Shift a variable.

Retuns the value of the variable given plus the shift amount as defined in the table of shifts. Variables shifted are reta, f1, f3, wstot, ws3, and weta2. All other variable will just return the input value.

Parameters:

	eT	The eT value of the electron.
	eta	The eta value of the electron.
	var	enum member corresponding to the variable. Type is ElePIDNames::Var
	val	The unshifted value of the variable.

Returns:

The shift value for the current electron/variable.

shiftVarByBin(), shiftStruct()

double TElectronMCShifterTool::shiftVarByBin	(	int	eTBin,
		int	etaBin,
		ElePIDNames::Var	var,
		double	val
	)

Shift a variable by the eT and eta bins.

Parameters:

	eT	The eT bin of the electron [0-5].
	eta	The eta bin of the electron[0-8].
	var	enum member corresponding to the variable. Type is ElePIDNames::Var
	val	The unshifted value of the variable.

Returns:

The shift value for the current electron/variable.
