# This is a simple simulation example showing how to run event simulation using

# the Pythia8 event generator in heavy-ion mode and use an external custom trigger.

# The external trigger makes use of the `DeepTrigger` functionality to allow the

# user to access the internals of the event generator to define the trigger.

#

# In this example, information about the impact parameter of the currently-generated

# Pythia8 heavy-ion event is used.

# The trigger selection defines impact parameters to be accepted according to a

# min-max range that can be adjusted from the command line.

# The definition and configuration of the external `DeepTrigger` is performed by

# the function `trigger_impactb_pythia8(double bMin = 0., double bMax = 20.)`

# defined in the macro `trigger_impactb_pythia8.macro`.

# The macro file and function names are specified via `--configKeyValues` setting

# `TriggerExternal.fileName` and `TriggerExternal.funcName`, respectively.
