Detailed Description

C++ class to recalibrate the \(p_{T}\) of jets. Initialized with basic parameters and calculations done on vectors of jets from an event using the class methods.

Constructor & Destructor Documentation

JetRecalibrator()

JetRecalibrator	(	str	jecTag,
		str	jetType,
		bool	doResidualJECs,
		str	uncertType,
		int	upToLevel = 3
	)

Construct a new Jet Recalibrator object.

Parameters

jecTag	The JEC tag to identify the JEC files to load.
jetType	The type of jet - ex. AK8PFPuppi.
doResidualJECs	Flag to turn on or off the residual JECs
uncertType	Empty string for the total uncertainty but any uncertainty in the JEC file can be provided.
upToLevel	Correction level to apply. Options are 1, 2, or 3 (corresponding to L1, L2, L3). Defaults to 3.

Member Function Documentation

CalculateCorrection()

void CalculateCorrection	(	T	jet,
		float	fixedGridRhoFastjetAll
	)

Calculate the correction for a given jet and rho and store the value internally.

Parameters

jet	TIMBER jet struct (generated automatically by TIMBER's analyzer()) which stores the attributes of the jet (pt, eta, phi, tagging values, etc).
fixedGridRhoFastjetAll	Stored in the NanoAOD with this name as the branch name.

Returns

void

CalculateUncertainty()

void CalculateUncertainty	(	T	jet,
		float	delta = 1
	)

Calculate the correction uncertainty for a given jet and store the value internally. WARNING: CalculateCorrection must be run first.

Parameters

jet	TIMBER jet struct (generated automatically by TIMBER's analyzer()) which stores the attributes of the jet (pt, eta, phi, tagging values, etc).
delta	Multiplicative factor on the uncertainty. Defaults to 1.

GetCorrection()

float GetCorrection

(

)

Return the internally stored correction value that was calculated during CalculateCorrection.

Returns

float

GetUncertainty()

float GetUncertainty

(

)

Return the internally stored uncertainty value that was calculated during CalculateUncertainty.

Returns

float
