Detailed Description
base class for user-defined ordering of stable cones (used for prorgessive removal)
derived classes have to implement the () operator that returns the scale associated with a given jet.
It is also highly recommended to implement the is_larger() method whenever possible, in order to avoid rounding issues known to lead to possible infrared unsafeties.
The jets that are passed to this class will carry the structure of type SISConePlugin::StructureType which allows to retreive easily the following information:
vector<PseudoJet> constituents = jet.constituents(); unsigned int n_constituents = jet.structure_of<SISConePlugin::UserScaleBase>().size(); int index = jet.structure_of<SISConePlugin::UserScaleBase>().constituent_index(index i); const PseudoJet & p = jet.structure_of<SISConePlugin::UserScaleBase>().constituent(index i); double scalar_pt = jet.structure_of<SISConePlugin::UserScaleBase>().pt_tilde();

Member Function Documentation
◆ result()
|
pure virtual |
returns the scale associated with a given jet
"progressive removal" iteratively removes the stable cone with the largest scale
Implements fastjet::FunctionOfPseudoJet< double >.
◆ is_larger()
|
virtual |
returns true when the scale associated with jet a is larger than the scale associated with jet b
By default this does a simple direct comparison but it can be overloaded for higher precision [recommended if possible]
