Atlfast AntiKt

AntiKt is the new official ATLAS algorithm, despite it currently not being used in the standard reconstruction.

To produce TruthJets using AntiKt and output them into an AAN, i used the following fragment in my JobOptions:

from JetRec.JetGetters import *
make_StandardJetGetter('AntiKt', 0.5, 'Truth') 
from JetRec.JetRecConf import CBNTAA_Jet
from JetRec.JetRecConf import CBNTAA_JetTool
JetTool2 = CBNTAA_JetTool("JetTool")
Jet2 = CBNTAA_Jet("CBNT_AntiKt5TruthJets")
Jet2.InputJetCollection = "AntiKt5TruthJets"
Jet2.BlockTag = "AntiKt5TruthJets"
Jet2.Tools = [ JetTool2 ]
from AthenaCommon.AlgSequence import AlgSequence
topSequence = AlgSequence()
topSequence += Jet2

Producing AntiKt Atlfast jets is probably more complicated, and under study. --fruehr 15:28, 7 May 2009 (UTC)
