class AliITSUSegmentationPix: public AliITSsegmentation

 Default constructor, sizes in cm

 d-tor

  Returns pixel coordinates (ix,iz) for given coordinates (x,z counted from corner of col/row 0:0)
  expects x, z in cm.

  local transformation of real local coordinates (x,z)
  expects x, z in cm (wrt corner of col/row 0:0

 Transform from pixel to real local coordinates
 returns x, z in cm. wrt corner of col/row 0:0

 get column number (from 0) from local Z (wrt bottom left corner of the active matrix)

 convert column number (from 0) to Z coordinate wrt bottom left corner of the active matrix

 = operator

 copy constructor

returs x pixel pitch for a give pixel

 returns z pixel pitch for a given pixel (cols starts from 0)

 returns the neighbouring pixels for use in Cluster Finders and the like.

 Transformation from Geant detector centered local coordinates (cm) to
 Pixel cell numbers ix and iz.
 Input:
    Float_t   x        detector local coordinate x in cm with respect to
                       the center of the sensitive volume.
    Float_t   z        detector local coordinate z in cm with respect to
                       the center of the sensitive volulme.
 Output:
    Int_t    ix        detector x cell coordinate. Has the range
                       0<=ix<fNRow.
    Int_t    iz        detector z cell coordinate. Has the range
                       0<=iz<fNCol.
 Return:
   kTRUE if point x,z is inside sensitive volume, kFALSE otherwise.
   A value of -1 for ix or iz indecates that this point is outside of the
   detector segmentation as defined.

 Transformation from Detector cell coordiantes to Geant detector centered
 local coordinates (cm).
 Input:
 Int_t    ix        detector x cell coordinate. Has the range 0<=ix<fNRow.
 Int_t    iz        detector z cell coordinate. Has the range 0<=iz<fNCol.
 Output:
 Float_t   x        detector local coordinate x in cm with respect to the
                    center of the sensitive volume.
 Float_t   z        detector local coordinate z in cm with respect to the
                    center of the sensitive volulme.
 If ix and or iz is outside of the segmentation range a value of -0.5*Dx()
 or -0.5*Dz() is returned.

 Transformation from Detector cell coordiantes to Geant detector centerd
 local coordinates (cm).
 Input:
 Int_t    ix        detector x cell coordinate. Has the range 0<=ix<fNRow.
 Int_t    iz        detector z cell coordinate. Has the range 0<=iz<fNCol.
 Output:
 Double_t   xl       detector local coordinate cell lower bounds x in cm
                    with respect to the center of the sensitive volume.
 Double_t   xu       detector local coordinate cell upper bounds x in cm
                    with respect to the center of the sensitive volume.
 Double_t   zl       detector local coordinate lower bounds z in cm with
                    respect to the center of the sensitive volulme.
 Double_t   zu       detector local coordinate upper bounds z in cm with
                    respect to the center of the sensitive volulme.
 If ix and or iz is outside of the segmentation range a value of -0.5*DxActive()
 and -0.5*DxActive() or -0.5*DzActive() and -0.5*DzActive() are returned.

 returns chip number (in range 0-4) starting from channel number

 returns chip number (in range 0-4) starting from local Geant coordinates

 returns the number of chips containing a road defined by given local Geant coordinate limits
