Class Description

                                                                      
 MCDiag                                                               
                                                                      
 The MCDiag class produces a stream of N particles with their         
 momentum spread out in magnitude and direction. The resulting        
 particles are output to a file in StdHep format.

MCDiag(char* ofile):m_MagSpread(0.0),m_CosThSpread(0.0),m_PhiSpread(0.0),m_NumParticles(1), m_xpoint(0),m_ypoint(0),m_zpoint(0),m_prod_time(0)

 Default constructor

void Set_Seed(UInt_t seed)

 Set the seed of the random number generator. If zero then seed
 is set to current machine clock

void Set_Spread(Double_t magspread, Double_t costhspread, Double_t phispread)

 The user is prompted for the momentum spread parameters

void Set_Momentum(Double_t mag, Double_t costheta, Double_t phi)

 Sets the mean components of the momentum vectors

void Set_Start_Point(Double_t xpoint, Double_t ypoint, Double_t zpoint)

 Sets the starting point of the particles(s).
 Default is (0,0,0) aka the IP.

void Set_Production_Time(Double_t time)

 Sets the time of production of the particles(s).
 Default is 0.0

void Set_Particles(Int_t num)

 Sets the number of particles

void Set_Type(Int_t type)

 Sets the particle type. NOTE: Must use StdHep numbering scheme.Particle
 mass is set from type

Int_t getEvent(Event* event)

Int_t doit()

 Create the stream of Particles

Int_t spew(char* ofile)const

 Save the particle data into the hepevt common block
 Write the common block out ot file using StdHepXdrWrite()

void cleanup()

 Closes the output stream.
