class AliMUONClusterSplitterMLEM: public TObject

 \class AliMUONClusterSplitterMLEM

 Splitter class for the MLEM algorithm. Performs fitting procedure
 with up to 3 hit candidates and tries to split clusters if the number
 of candidates exceeds 3.

Function documentation

AliMUONClusterSplitterMLEM(Int_t detElemId, TObjArray* pixArray, Double_t lowestPixelCharge, Double_t lowestPadCharge, Double_t lowestClusterCharge)

 Constructor

~AliMUONClusterSplitterMLEM()

 Destructor

AddBin(TH2* mlem, Int_t ic, Int_t jc, Int_t mode, Bool_t* used, TObjArray* pix)

 Add a bin to the cluster

AddCluster(Int_t ic, Int_t nclust, TMatrixD& aijcluclu, Bool_t* used, Int_t* clustNumb, Int_t& nCoupled)

 Add a cluster to the group of coupled clusters

BinToPix(TH2* mlem, Int_t jc, Int_t ic)

 Translate histogram bin to pixel

ChargeIntegration(Double_t x, Double_t y, const AliMUONPad& pad)

 Compute the Mathieson integral on pad area, assuming the center
 of the Mathieson is at (x,y)

Fcn1(const AliMUONCluster& cluster, Int_t& npar, Double_t* gin, Double_t& f, Double_t* par, Int_t iflag)

 Computes the functional to be minimized

Double_t Param2Coef(Int_t icand, Double_t coef, Double_t* par) const

 Extract hit contribution scale factor from fit parameters

Fit(const AliMUONCluster& cluster, Int_t iSimple, Int_t nfit, const Int_t* clustFit, TObjArray** clusters, Double_t* parOk, TObjArray& clusterList, TH2* mlem)

 Steering function and fitting procedure for the fit of pad charge distribution

Split(const AliMUONCluster& cluster, TH2* mlem, Double_t* coef, TObjArray& clusterList)

 The main steering function to work with clusters of pixels in anode
 plane (find clusters, decouple them from each other, merge them (if
 necessary), pick up coupled pads, call the fitting function)

Merge(const AliMUONCluster& cluster, Int_t nForFit, Int_t nCoupled, const Int_t* clustNumb, const Int_t* clustFit, TObjArray** clusters, TMatrixD& aijcluclu, TMatrixD& aijclupad)

 Merge the group of clusters with the one having the strongest coupling with them

MinGroupCoupl(Int_t nCoupled, const Int_t* clustNumb, const TMatrixD& aijcluclu, Int_t* minGroup)

 Find group of clusters with minimum coupling to all the others

SelectPad(const AliMUONCluster& cluster, Int_t nCoupled, Int_t nForFit, const Int_t* clustNumb, const Int_t* clustFit, const TMatrixD& aijclupad)

 Select pads for fit. If too many coupled clusters, find pads giving
 the strongest coupling with the rest of clusters and exclude them from the fit.

UpdatePads(const AliMUONCluster& cluster, Int_t nfit, Double_t* par)

 Subtract the fitted charges from pads with strong coupling

AliMUONClusterSplitterMLEM(Int_t detElemId, TObjArray* pixArray, Double_t lowestPixelCharge, Double_t lowestPadCharge, Double_t lowestClusterCharge)

void SetDebug(Int_t debug)

 Set debug level

{ fDebug = debug; }

AliMUONClusterSplitterMLEM& operator=(const AliMUONClusterSplitterMLEM& )

 will not be implemented
