  2. In Top_analyze or Athena / rcp / D0ChunkAnalyze.rcp // Select the jet finding algorithm // (Run II 0.5 cone algorithm with preclustering) string JetAlgo_type = "PreSCilcone" string JetAlgo_names = ( "towers" "coneSize" "Radius_of_Cone" "Min_Jet_ET") float JetAlgo_values = ( 0. 0.3 0.5 8. ) // // Parameter for Jet Energy Scale Correction bool JetEnergyScale = true bool JetEnergyScale_muontag = true change to : partons particles then these must be changed to false

  3. # Standard block names for reco_analyze There are some standard rcp used in reco_analyze for the jet algorithms ran in d0reco in which we have defined a scheme for the naming of the prefix: JAXY, where * A is the algorithm: o K for kT o C for cone o S for simple cone o N for CellNN o E for Emnn * X represent the type of data used: o C for calorimeter data o M for Monte Carlo particles o P for Monte Carlo partons * Y represents a parameter set That translates into : * JCCG : RUN I cone on cal towers R=0.7, with NN preclustering * JCCH : RUN I cone on cal towers R=0.5, with NN preclustering * JCCI : RUN I cone on cal towers R=0.3, with NN preclustering * JCC7 : RUN I cone on cal towers R=0.7, with simple cone preclustering * JCM7 : RUN I cone on MC particles R=0.7, with simple cone preclustering

  4. JAXY * A is the algorithm: o K for kT o C for cone o S for simple cone o N for CellNN o E for Emnn * X represent the type of data used: o C for calorimeter data o M for Monte Carlo particles o P for Monte Carlo partons * Y represents a parameter set * JCCA : RUN II cone on cal towers R=0.7 * JCMG : idem on MC particles * JCPG : idem on MC partons * JCCB : RUN II cone on cal towers R=0.5 * JCMB : idem on MC particles * JCPB : idem on MC partons * JCCC : RUN II cone on cal towers R=0.3 * JCMC : idem on MC particles * JCPC : idem on MC partons * JKC1 : kT RUN I on cal towers D=1 * JKM1 : idem on MC particles * JKCA : kT RUN II on cal towers D=1 * JKMA : idem on MC particles * JKCB : kT RUN II on cal towers D=0.4 * JKMB : idem on MC particles
