Class Description

 Implementation version 1 of algorithm class to construct PHOS track segments
 Associates EMC and PPSD clusters
 Unfolds the EMC cluster

*-- Author: Dmitri Peressounko (RRC Ki & SUBATECH)

AliPHOSTrackSegmentMakerv1()

 ctor

~AliPHOSTrackSegmentMakerv1()

 dtor

Bool_t FindFit(AliPHOSEmcRecPoint * emcRP, int * maxAt, Float_t * maxAtEnergy, Int_t nPar, Float_t * fitparameters)

 Calls TMinuit to fit the energy distribution of a cluster with several maxima

void FillOneModule(DigitsList * Dl, RecPointsList * emcIn, TObjArray * emcOut, RecPointsList * ppsdIn, TObjArray * ppsdOutUp, TObjArray * ppsdOutLow, Int_t & phosmod, Int_t & emcStopedAt, Int_t & ppsdStopedAt)

 Unfold clusters and fill xxxOut arrays with clusters from one PHOS module

Float_t GetDistanceInPHOSPlane(AliPHOSEmcRecPoint * emcclu,AliPHOSPpsdRecPoint * PpsdClu, Bool_t &toofar)

 Calculates the distance between the EMC RecPoint and the PPSD RecPoint

void MakeLinks(TObjArray * emcRecPoints, TObjArray * ppsdRecPointsUp, TObjArray * ppsdRecPointsLow, TClonesArray * linklowArray, TClonesArray *linkupArray)

 Finds distances (links) between all EMC and PPSD clusters, which are not further apart from each other than fR0

void MakePairs(TObjArray * emcRecPoints, TObjArray * ppsdRecPointsUp, TObjArray * ppsdRecPointsLow, TClonesArray * linklowArray, TClonesArray * linkupArray, TrackSegmentsList * trsl)

void MakeTrackSegments(DigitsList * DL, RecPointsList * emcl, RecPointsList * ppsdl, TrackSegmentsList * trsl)

 Makes the track segments out of the list of EMC and PPSD Recpoints and stores them in a list

Double_t ShowerShape(Double_t r)

 Shape of the shower (see PHOS TDR)
 If you change this function, change also the gradien evaluation  in ChiSquare()

void UnfoldClusters(DigitsList * DL, RecPointsList * emcIn, AliPHOSEmcRecPoint * iniEmc, Int_t nMax, int * maxAt, Float_t * maxAtEnergy, TObjArray * emcList)

 Performs the unfolding of a cluster with nMax overlapping showers
 This is time consuming (use the (Un)SetUnfolFlag()  )
