  TOF hit  : member variables
  fTrack   :
  fX       : X coordinate of the hit in the Master Reference Frame (LAB Frame)
  fY       : Y coordinate of the hit in the Master Reference Frame (LAB Frame)
  fZ       : Z coordinate of the hit in the Master Reference Frame (LAB Frame)
  fSector  : Number of the TOF Sector which belongs the hit
  fPlate   : Number of the TOF Plate or Module which belongs the hit
  fStrip   : Number of the TOF Strip which belongs the hit
  fPadx    : Number of the pad in the strip along the x-axis - in the strip reference frame
             - where hit is produced
  fPadz    : Number of the pad in the strip along the z-axis - in the strip reference frame
             - where hit is produced
  fPx      : x-director cosine of the Charged Particle Momentum when hit is
             produced - expressed in the Master Reference Frame (LAB Frame) -
  fPy      : y-director cosine of the Charged Particle Momentum when hit is
             produced - expressed in the Master Reference Frame (LAB Frame) -
  fPz      : z-director cosine of the Charged Particle Momentum when hit is
             produced - expressed in the Master Reference Frame (LAB Frame) -
  fPmom    : Modulus of the Charged Particle Momentum when hit is produced
  fTof     : Time of Flight i.e. the time between the charged particle is produced and this
             particle produce the hit on the TOF sensible volume (pad)
  fDx      : Distance of the hit from the pad edge along x-axis
  fDy      : y coordinate of the hit in the pad refernce frame
  fDz      : Distance of the hit from the pad edge along z-axis
  fIncA    : Incidence Angle between the Normal to the sensible volume where hit
             is produced (pad) and the Momentum Direction of the Charged Particle which
             produces the hit
  fEdep    : Energy released by charged particle on the sensible TOF volume where hit is
             produced
