This is a first attempt at comparing the performance of the CAL shower shape analysis between pass7 and pass8.

The file used for the work are:

For Pass7:

AG-GR-v17r31-StdCuts-merit.root

BKG-GR-v17r31-StdCuts-merit.root

where StdCuts are: FswGamState == 0&&  CalEnergyRaw>  5&& TkrNumTracks>  0&&  CalCsIRLn>  4.

For Pass8:

AG-GR-v20r3p4-OVL

BKG-GR-v20r3p4-OVL

I include the following precuts to the allGamma sample for both Pass7 and Pass8:

FswGamState==0 && TkrNumTracks > 0 && (CalEnergyRaw > 5 && CalCsIRLn > 4) && CTBCPFGamProb>0

note for Pass8 CalEnergyRaw is substutited by CalUberEnergy and I have added the cut on CTBCPFGamProb because it is necessary that the sample of events pass the

Cpf selection before I can compare the Pass7 and Pass8 selection in the CAL.

To the BKG sample I include in addition to the above selection the condition that there not be gamma's in the sample, i.e. a cut on

McSourceId != 7000

The selection conditions assigned to each node are defined below:

veto BackSeal: ((Cal67Sum - 66.)/33.5)^2 + ((Cal67Diff + .4)/7.2)^2 < 1.2 & CalLLRms < 30

veto LowE: CalEdgeEnergy>0 & CalEdgeEnergyRatio >  (LogCalEnergyRaw -.5)/2.

filter VTXSplit: VtxAngle > 0

veto VtxSideSeal: (CalDeltaEdgeEnergy < .6  & CalDeltaEdgeEnergy < 6/CalEdgeEnergy & CalEdgeEnergy < 190)

veto Vtx: (CTBTkrCoreCalDoca<32.3 | (CTBTkrCoreCalDoca<152 & XtalRmsTkrCoreDoca<-10)) & XtalRmsTkrCoreDoca < (2- .15*CTBTkrCoreCalDoca)  & Tkr1CoreHC > 0

filter notVTXSplit: VtxAngle == 0

veto TkrSideSeal: (CalDeltaEdgeEnergy < .75 | (CalDeltaEdgeEnergy < .95 - (30./(CalEdgeEnergy+20))^2 & CalEdgeEnergy < 300)) & CalDeltaEdgeEnergy < (1.1 - CalEdgeEnergy/200)

filter nTkrFront: TkrNumTracks > 1 && Tkr1FirstLayer < 5 &&(CTBTkrCoreCalDoca<40.56 | (CalXtalRatio<0.105 & EvtECalTransRms<3.45))

filter nTkrBack: "TkrNumTracks > 1 && Tkr1FirstLayer > 5 && ((CTBTkrSHRCalAngle>0.142 && CTBTkrCoreCalDoca<16.7) | (CTBTkrSHRCalAngle<0.142 & XtalRmsTkrCoreDoca<-15.4))

filter 1TkrFront: (TkrNumTracks == 1) && Tkr1FirstLayer < 5 && (EvtECalTrackDoca < 2.13 || CTBTkrEnergyFrac > 0.285)

filter 1TkrBack: (TkrNumTracks == 1) && Tkr1FirstLayer > 5 && !(XtalRmsTkrCoreDoca > -3 && CalTrkXtalRmsE > 12)

Below are some plots on the sequential selection efficiency for each node in the CAL worksheet, I apologize for the low contrast yellow line in the plots!
