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 R0.7, with NN
preclustering JCCH RUN I cone on cal
towers R0.5, with NN preclustering JCCI
RUN I cone on cal towers R0.3, with NN
preclustering JCC7 RUN I cone on cal
towers R0.7, with simple cone preclustering
JCM7 RUN I cone on MC particles R0.7, with
simple cone preclustering
