#
# This module defines mapping rules from nominal Phase-I L1Calo thresholds
# (target 50% efficiency point) to the actual cut that will be applied
# to the TOB ET. This allows tuning of the thresholds transparently via
# changes to the L1 menu, without adjusting the names of chains.
#
# The threshold mapping should be used for both multiplicity threshold
# definitions and for the threshold cuts on TOBs in topo algorithms.
