# 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
