# Run just the algorithm part of the eclGammaGammaE calibration, which calibrates the single crystal
# energy response using e+e- --> gamma gamma events. Runs on the output produced by
# run_eclGammaGammaE_collector.py.
# Standard usage: algo.performFits = True; performs a Novosibirsk fit on specified crystals to
# extract the calibration constant.
# algo.performFits = False just copies the input histograms into the output file for debugging.
 
# algo.storeConst = 0 fills database payloads ECLCrystalEnergyGammaGamma or ECLExpGammaGammaE
#                     (if findExpValues=True) for all crystals with successful fits and writes to localdb
# algo.storeConst = 1 fills writes the payloads only if every crystal in specified range is successful
# algo.storeConst = -1 do not write to the database
 
# Specified output file contains many diagnostic histograms.
