Class Description

  HEnergyLossCorrPar

  Container class keep parameters for energy loss correction


  Float_t getDeltaMom(Int_t pId, Float_t mom, Float_t theta);
     Function getDeltaMom returns the correction value (delP) for momentum.
     Parameters: - pId is particle ID. If parameter pId is not correct
                 function getDeltaMom returns 0.
                 - mom is Runge-Kutta reconstructed momentum (MeV).
                 - theta is theta angle in the interval [15;87] (degrees).
                 If parameter theta is out of this interval
                 function getDeltaMom returns 0.

  Float_t getCorrMom(Int_t pId, Float_t mom, Float_t theta) {
          return mom+getDeltaMom(pId,mom,theta);}
     Function getCorrMom returns the corrected momentum.
     Parameters have the same meanings as for function getDeltaMom.


  Alternative method of getting parameters (without usage of runTimeDb):

  Bool_t  setDefaultPar(const char *rn="jan04");
     Function setDefaultPar sets default values to parameters
     for corresponding beam team.

  Example:
        HEnergyLossCorrPar enLossCorr;
        enLossCorr.setDefaultPar("jan04"); // or "nov02", or "aug04"
        Float_t delP;
        ..............................
        beginning of your loop;
          ..............................................
          delP = enLossCorr.getDeltaMom(14, mom, theta);
          ..............................................
        end of your loop;

 constructor

 initializes the container from an input

 writes the container to an output

 puts all parameters to the parameter list, which is used by the io

 gets all parameters from the parameter list, which is used by the io
