[out]	TVector2	The vector from the circle center to the corresponding hit

Definition at line 116 of file PndApolloniusTriplet.h.

{ return TVector2(hit->GetX() - fTrack.X(), hit->GetY() - fTrack.Y()); }

IsClockwise()

void PndApollonius::TripletSolution::IsClockwise

(

)

Determins the rotation of the circle, i.e. if the particle mooves clockwise or not.

IsReasonableHit()

bool PndApollonius::TripletSolution::IsReasonableHit	(	FairHit *	CurrentHit,
		FairHit *	PriviousHit
	)

Tests if a specific hit is a reasonable hit of the track (based on the angle and the rotation of the track)

Parameters

[in]	CurrentHit	The current hit
[in]	PriviousHit	The previous hit of the track

SortAllHits()

void PndApollonius::TripletSolution::SortAllHits

(

PndSttGeometryMap *
