Member Function Documentation

Double_t MySystematics::egamma_resolution

(

const Double_t

et

)

[inline]

Gaussing smearing in the resolution of electron/photon smearing of ET with some sigma specified/recommended this method returns the smeared electron/photon ET

Definition at line 19 of file MySystematics.ixx.

Double_t MySystematics::muon_resolution

(

const Double_t

pt

)

[inline]

Gaussing smearing in the resolution smearing in pt with some sigma specified/recommended This method return the smeared muon PT (in GeV)

Definition at line 33 of file MySystematics.ixx.

Double_t MySystematics::jet_resolution	(	const Double_t	e,
		const Double_t	eta
	)			[inline]

Gaussing smearing in the resolution smearing of et with some sigma specified/recommended This method returm the smeared jet E (in GeV) values are eta dependent

Definition at line 65 of file MySystematics.ixx.

Double_t MySystematics::taujet_resolution

(

const Double_t

e

)

[inline]

Gaussing smearing in the resolution smearing of et with some sigma specified/recommended This method returm the smeared TauJet E (in GeV)

Definition at line 81 of file MySystematics.ixx.

Double_t MySystematics::energy_scale	(	const Double_t	pT,
		const Double_t	f
	)			[inline]

Energy scale - boost pT with corresponding f+ nad f-

Definition at line 92 of file MySystematics.ixx.

Bool_t MySystematics::is_detected

(

const Double_t

f

)

[inline]

Efficiency: account for the efficiency uncertainty (see "error" in the table) with the appropriate analytical calculation (event yield). test both approach: should get similar result

Definition at line 107 of file MySystematics.ixx.

Bool_t MySystematics::is_bjet

(

const Double_t

f_minus

)

[inline]

b-tagging efficiency uncertainty kill randomly the available b-tagged jets according to the additional inefficiency probability reported (1- f-)

Definition at line 120 of file MySystematics.ixx.

Double_t MySystematics::metCorrection_x	(	const Double_t	aodPx,
		const Double_t	correctedPx
	)			[inline]

Correct the missing energy according to the reconstructed muon: For Resolution and Energy scale: ETM_x_new = ET_x_fromAOD + pxmu_fromAOD - pxmu_new Here you pass the X and Y component separately You have to add the original MET your self
