# There are two ways you can use this script:
# 1. Provide parameters from command line:
#   basf2 run_eclBhabhaT_collector.py -i "/path/to/input/files/*.root" -o collector_output.root
#
# 2. Set parameters directly in steering file.
#   Change INPUT_LIST and OUTPUT variables.
#   (Multiple files can be easily added with glob.glob("/path/to/your/files/*.root"))
#   And then call
#   basf2 run_eclBhabhaT_collector.py
