CAL Shower Shape Analysis Pass7 vs Pass8

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

Below are some plots on the sequential selection efficiency for each node in the CAL worksheet.
