Detailed Description

Description: Holds the coefficients of a polynomial that describes variation of the global containment effect as afunction of eta

Usage example(for real code see CalibCalorimetry/EcalCorrectionModules/test) :

ESHandle<EcalGlobalShowerContainmentCorrectionsVsEta> pGapCorr;
iESetup.get<EcalGlobalShowerContainmentCorrectionsVsEtaRcd>().get(pGapCorr);
 
double correction3x3 = pGapCorr->correction3x3(centerXtal,mathpoint);
double correction5x5 = pGapCorr->correction5x5(centerXtal,mathpoint);

correction3x3()

const double EcalGlobalShowerContainmentCorrectionsVsEta::correction3x3

(

const DetId &

xtal

)

const

The correction factor for 3x3 matrix.

Parameters

pos	is the distance in cm from the center of the xtal as calculated in RecoEcal/EgammaCoreTools/interface/PositionCalc.h The valid return value is in the range (0,1] (divide by this value to apply the correction) Returns -1 if correction is not avaiable for that xtal
