class THaBeamEloss: public THaElossCorrection, public THaBeamModule


 THaBeamEloss

 Correct energy loss of the beam by a constant. This is basically trivial,
 but useful to have to provide input for kinematics modules.
 More advanced corrections can be implemented by inheritance from
 this module.

Function documentation

THaBeamEloss(const char* name, const char* description, const char* input_beam = "")
 Normal constructor.
~THaBeamEloss()
 Destructor
void CalcEloss(THaBeamInfo* beamifo)
 Compute the mean energy loss for the beam given in beamifo.

 Currently, we use a very simple algorithm that computes
 the energy loss based on a fixed material thickness.
 Only the beta dependence of the energy loss is used,
 but there are no corrections for angle, pathlength etc.

 May be overridden by derived classes as necessary.
void Clear(Option_t* opt = "")
 Clear all event-by-event variables.
THaAnalysisObject::EStatus Init(const TDatime& run_time)
 Initialize the module.
 Locate the input beam module named in fInputName and save pointer to it.
 Extract mass and charge of the beam particles from the input.
Int_t DefineVariables(THaAnalysisObject::EMode mode = kDefine)
 Define/delete global variables.
Int_t Process(const THaEvData& )
 Calculate corrections and adjust the track parameters.
