class AliGenSTRANGElib: public AliGenLib

  AliGenSTRANGElib class contains parameterizations of the
  kaon, phi and hyperon (Lambda, Anti-Lambda, Xi, anti-Xi, Omega,
  anti-Omega)  for the PPR study of the strange particle production.
  These parameterizations are used by the
  AliGenParam  class:
  AliGenParam(npar, param,  AliGenSTRANGElib::GetPt(param),
                            AliGenSTRANGElib::GetY(param),
                            AliGenSTRANGElib::GetIp(param) )
  param represents the particle to be simulated.

  Pt distributions are calculated from the transverse mass scaling
  with Pions, using the PtScal function taken from AliGenMUONlib
  version aliroot 3.01

Function documentation

Double_t PtScal(Double_t pt, Int_t np)
 Mt-scaling
 Function for the calculation of the Pt distribution for a
 given particle np, from the pion Pt distribution using the
 mt scaling. This function was taken from AliGenMUONlib
 aliroot version 3.01, and was extended for hyperons.
 np = 1=>Pions 2=>Kaons 3=>Etas 4=>Omegas 5=>ETA' 6=>PHI
      7=>BARYONS-BARYONBARS
      8=>Lambda-antiLambda
