A cut is applied to select good gamma rays:
"FswGamState==0 && TkrNumTracks > 0 && CalEnergyRaw > 5 && CalCsIRLn>4 && CTBCORE>0 && CTBBestEnergyProb>0.1 && CTBClassLevel>2 && FT1ZenithTheta>112 && FT1ZenithTheta<115"
Top panel of plot below shows the distribution of (log10 of) deposited energy for:
all sample, events with at least 1 ghost-tagged xtal, events with at least 1 ghost-tagged xtal & > 50% of ghost-tagged energy fraction
Bottom panel of plot below shows the correlation between number of ghost-tagged xtals and ghost-tagged energy (zero suppressed)
It looks like that almost all good gamma events have at least one ghost-tagged xtal and even requiring a large ghost-tagged energy we select a large fraction of events
