class AtlK0sFinder: public AtlKinFitterTool


 K0s decay finder class

 K0s will be reconstructed while looping over all secondary vertices
 with 2 daughter tracks. Oppositely charged tracks will be added to
 K0s-List in AtlEvent while same charged tracks will give a first
 first estimation for background K0s and will be stored in a TList
 called fKkgK0sDecays.
 The Decay decision will be done either by a cut bassed reconstruction
 or by using the kinemativ fitter. Switching is possible by a Flag
 EMode (kCutBased, kKinFit) that can be set in the constructor via
 SetMode(EMode)

Function documentation

AtlK0sFinder(const char* name, const char* title)
 Default constructor
~AtlK0sFinder()
 Default destructor
void SetBranchStatus()
 Switch on needed branches
void BookHistograms()
 Book histograms
Bool_t AnalyzeEvent()
 Event analysis
void ReconstructK0sCutBased()
 Cut Based K0s reconstruction
void ReconstructK0sKinFit()
 K0s reconstruction from track-pairs assuming being pions using KinFitter
void FillHistograms()
 Fill histograms
void SetCutDefaults()
 Selection cut defaults and Constraint parameters
void PrintCutValues()
Int_t DoTruthMatch(AtlK0sDecayPiPi* K0sCandidate)
 retuns 1 in case of true K0s, -1 if not
 returns 0 if no decision possible (see fMatchingProb_min)
Bool_t IsLambdaCandidate(HepVertex* vtx)
 Return true, if the given vertex is already assigned
 to a lambda decay. Return false otherwise or if
 there are no  lambda decays (eg. the Lambda finder didn't run).
void FillHistograms_MCTruthStudy(AtlK0sDecayPiPi* K0sCandidate, 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 (K0s candiates that fulfill
 the monte-carlo truth-matching as well as those that fail)
void Terminate()
AtlK0sFinder(const char* name, const char* title)
void SetMode(AtlK0sFinder::EMode mode = kKinFit)
{ fMode = mode; }
void SetDebugMode(Bool_t DebugMode = kFALSE)
{ fDebugMode = DebugMode; }
Bool_t IsDebugRun()
{ return fDebugMode; }
