Constructor & Destructor Documentation

fastjet::ATLASConePlugin::ATLASConePlugin	(	double	radius,
		double	seedPt_in = 2.0,
		double	f_in = 0.5
	)		[inline]

Main constructor for the ATLASCone Plugin class.

Apparently the default parameters in the ATLAS software are the ones used here. SpartyJet uses a radius of 0.7, a seed threshold of 1 GeV and an overlap threshold of 0.75 For the ATLAS SW defaults, see http://atlas-sw.cern.ch/cgi-bin/viewcvs-atlas.cgi/groups/JetRoutines/SpartyJet/atlas/ in the JetdoneFinderTools.cxx (rev1.1) and JetSplitMergeTool.cxx (rev1.1) For SpartyJet, see atlas/ConeFinderTool.h

Finally, to agree with FastJet standards, we do not specify a default R, that in the ATLAS code is 0.7
