class AliPHOSFastRecParticle: public TParticle
A Particle modified by PHOS response and produced by AliPHOSvFast To become a general class of AliRoot ? -- This is also a base class for AliPHOSRecParticle produced by AliPHOSPIDv1 The rec.particle type is to be defined by AliPHOSvFast or AliPHOSPIDv1 -- *-- Author: Yves Schutz (SUBATECH)

Function documentation
Int_t DistancetoPrimitive(Int_t px, Int_t py)
Compute distance from point px,py to a AliPHOSFastRecParticle considered as a Tmarker Compute the closest distance of approach from point px,py to this marker. The distance is computed in pixels units.
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
Execute action corresponding to one event This member function is called when a AliPHOSFastRecParticle is clicked with the locator
Bool_t IsPhoton(TString purity = "low") const
