class AtlPhiFinder: public AtlKinFitterTool


 Phi decay finder class

 Phi will be reconstructed while looping over all two track combinations
 which are leaving the primary vertex. For the signal the leaving Kaon tracks
 have to be oppositely charged (added to Phi-List in AtlEvent), same
 charged tracks will be put in a TList called fBkgPhiDecays for the
 background.
 The selection can be done by a cut based method or a kinemativ fitter.
 Switching is possible by a Flag EMode (kCutBased, kKinFit) that can
 be set in the constructor via SetMode(EMode).
 Some Cut Values have to be set external, look at SetCutDefaults.
 You can also run in a Debug mode to get more information about your
 analysis.

 some cut criteria have to be set external
 have a look at SetCutDefaults()
 others can be changed in SetCutDefaults()
void ReconstructPhiKinFit()
 Phi reconstruction from track-pairs assuming being Kaons using KinFitter
void FindSharedTracks()
void FillHistograms()
 Fill histograms (not all, some are filled in Reconstruct)
void SetCutDefaults()
 Selection cut defaults and Constraint parameters

 external cuts:
 fPhi_M_min, fPhi_M_max:
                     e.g.:  for Cutbased: 0.950..1.250
                            for KinFit  : 1.015..1.025
 Quality of VtxFit: fVertexChi2ovNDoF_max:
                     e.g.:  normal:   1.5
                            DebugRun: 5.0
 Quality of TrkFit: fTrackChi2ovNDoF_max:
                     e.g.:  normal:   1.5
                            DebugRun: 3.8
 Angle between Trks (only for KinFit): fAngle_max: e.g.: 0.3 (rad) (seems to less nice for purity)
 Quality of kinematic Fit: fKinFitPvalue_min: e.g:   0.10
 Quality of Truth Matching: fMatchingProb_min: e.g.: 0.95
void PrintCutValues()
void Terminate()
Int_t DoTruthMatch(AtlIDTrack* trk1, AtlIDTrack* trk2)
 retuns 1 in case of true Phi, -1 if not
 returns 0 if no decision possible (see fMatchingProb_min)
void FillHistograms_MCTruthStudy(AtlPhiDecayKK* PhiCandidate, char type)
 !!! key 'type' must be "s" for signal or "b" for background !!!
 !!! routine could only be processed in case of a mc sample  !!!

 fills several histograms like pointing angle, invariant mass,
 decay angle, ... separately for bkg and signal (Phi candiates that fulfill
 the monte-carlo truth-matching as well as those that fail)
Float_t Delta_dEdx(AtlIDTrack* trk1)
AtlPhiFinder(const char* name, const char* title)
void SetMode(AtlPhiFinder::EMode mode = kKinFit)
 Test-mode or Run-mode
{ fMode = mode; }
void SetDebugOutput(Bool_t mode = kFALSE)
{ fDebug = mode; }
Bool_t IsDebugRun()
{ return fDebug; }
