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.
