# Usage: basf2 -i inputFile run_eclGammaGammaE_collector.py
# option: basf2 -i inputFile run_eclGammaGammaE_collector.py OutputFile.root
 
# Run just the collector part of the eclGammaGammaE calibration, which calibrates the single crystal
# energy response using gamma gamma events.
# Input file should be a gamma gamma skim (or MC) and include ECLDigits, ECLCalDigits, ECLClusters,
# and tracks (to veto Bhabhas).
# Output histograms are written to specified output file. Default is eclGammaGammaECollectorOutput.root
# run_eclGammaGammaE_algorithm.py is then used to perform calibration using these histograms, or to simply copy
# them to an output file.
