	# This file contains tunes to UE data from CDF and ATLAS at 900 GeV,
	# 1.8 TeV and 7.0 TeV. Moreover, we provide a suggestion for 2.76 TeV
	# and 14 TeV runs, which extrapolates between other tunes.
	#
	# NOTE: You have to uncomment some lines in this file, depending on your
	# center-of-mass energy! Please read the instructions below carefully.
