Class Description

  Implementation version 1 of the clusterization algorithm

*-- Author: Yves Schutz (SUBATECH)

AliPHOSClusterizerv1()

 default ctor (to be used)

Int_t AreNeighbours(AliPHOSDigit * d1, AliPHOSDigit * d2)

 Gives the neighbourness of two digits = 0 are not neighbour but continue searching
                                       = 1 are neighbour
                                       = 2 are not neighbour but do not continue searching
 neighbours are defined as digits having at least common vertex
 The order of d1 and d2 is important: first (d1) should be a digit already in a cluster
                                      which is compared to a digit (d2)  not yet in a cluster

void FillandSort(const DigitsList * dl, TObjArray * tl)

 Copies the digits with energy above thershold and sorts the list
 according to increasing Id number

void GetNumberOfClustersFound(Int_t * numb)

 Fills numb with the number of EMC  (numb[0]) clusters found
                               PPSD (numb[1]) clusters found

Bool_t IsInEmc(AliPHOSDigit * digit)

 Tells if (true) or not (false) the digit is in a PHOS-EMC module

void MakeClusters(const DigitsList * dl, RecPointsList * emcl, RecPointsList * ppsdl)

 Steering method to construct the clusters stored in a list of Reconstructed Points
 A cluster is defined as a list of neighbour digits

void PrintParameters()

 Print the energy thresholds
