Detailed Description

Class for storing Vincia weights.

Member Function Documentation

int doVarNow	(	string	keyIn,
		enum AntFunType	antFunTypePhys,
		bool	isFSR
	)

Helper function for keyword evaluation.

Check variation for all branching types.

Check variation for specific branching type.

void init ( bool  doMerging )

overridevirtual

Initialize.

Check initPtr.

Merging on/off ?

List of all keywords recognised by Vincia.

Convert antFunTypePhys to keyword.

Clean up the names of requested variations.

Parse names of requested variations and check for keywords.

Safety check for non-sensible input.

Check input keywords against known ones.

If a weight with this name does not yet exist, book one.

Reimplemented from WeightsBase.

void scaleWeightVar	(	vector< double >	pAccept,
		bool	accept,
		bool	isHard
	)

Scale the uncertainty band weights.

Scaling functions. They determine what needs to be done, to which weight(s), and then call the relevant base class method: reweightValueByIndex.

Variations only pertain to hard process and resonance decays.
