# in this config below, we use the replace option to make
# the logger let out messages of severity ERROR (INFO level
# will be suppressed), and we want to limit the number to 10

# this config frament brings you 3 steps of the detector simulation:
# -- vertex smearing (IR modeling)
# -- G4-based hit level detector simulation
# -- digitization (electronics readout modeling)
# it returns 2 sequences : 
# -- psim (vtx smearing + G4 sim)
# -- pdigi (digitization in all subsystems, i.e. tracker=pix+sistrips,
#           cal=ecal+ecal-0-suppression+hcal), muon=csc+dt+rpc)

# please note the IMPORTANT: 
# in order to operate Digis, one needs to include Mixing module 
# (pileup modeling), at least in the 0-pileup mode
#
# There're 3 possible configurations of the Mixing module :
# no-pileup, low luminosity pileup, and high luminosity pileup
#
# they come, respectively, through the 3 config fragments below
#
# *each* config returns label "mix"; thus you canNOT have them
# all together in the same configuration, but only one !!!
