Run6 GammaJet Distributions

Jet and skim tree synchronization events = 1.145444e+07 (total statistics)

Events satisfying trigger condition = 2136249

Events after finding the best vertex = 1878846

Events after z vertex cut = 1507423 (+- 100 cm)

Events having two jets and one photon = 367153

Photon matched to one of the jets within a cone radius of 0.7 = 363443

Photon didn't match to any of the jets within a cone radius of 0.7 = 3710

Same side jet having barrel towers = 77265

GammaJet candidates after matching = 363443

GammaJet candidates for which away side jet was found = 301660

GammaJet candidates left after imposing detector eta cut on away side jet = 235144

GammaJet candidates after requiring pT>7GeV cut on the photon = 99553

GammaJet candidates after requiring pT>5GeV cut on the away side jet = 82286

Following distributions are based on this sample (82286)

pT distribution

Pseudorapidity distribution

Photon Jet Balance

Let us look at the numbers again.........

GammaJet candidates after requiring pT>5GeV cut on the away side jet = 82286

GammaJet candidates after track isolation cut = 54692

Away side jet neutral fraction < 0.9 = 53708

EMC isolation cut =21121

No barrel towers =17805

Numbers sorted into different preshower bins

pre1=0, pre2=0                                                                     pre1=0 pre2>0

pre1>0 and pre1<4 MeV                                                         pre1>=4MeV

Gamma candidates having no jet = 3928

Gamma candidates having one jet = 245250

Away side jet found for monojet event = 3991

Gamma candidates having three jets = 91183

Gamma candidates having four jets = 14895
