Detailed Description

Star Simple Kinematics Generator.

StarKinematics provides a simple event generator capable of injecting single particles, or distributions of particles, into a simulation.

Usage:

// Create primary generator (main steering code)
StarPrimaryMaker *primary = new StarPrimaryMaker();

// Create kinematics generator and add it to the main maker
StarKinematics *kine = new StarKinematics("kine");

// 0=throw (flat or distribution) in pseudorapidity [default]
// 1=throw (flat or distribution) in rapidity
kine->SetAttr( "rapidity", 1 );

primary->AddGenerator( kine );

// ... add other makers to chain

// Initialize the chain
chain -> Init();

for ( Int_t i=0;i<nevents;i++ )
{

   if ( option1 ) // Option 1: throw Npart muons flat in pt, eta, phi
   {
       kine->Kine(Npart, "muon+", 0., 10., -2.0, +2.0, -3.1415, +3.1415 );
   }
   if ( option2 ) // Option 2: add a single photon to the event
   {
       StarGenParticle *gamma = kine->AddParticle("gamma");
       // Set particle properties explicitly ...
       gamma->SetPx( 2.0 );
       gamma->SetPy( 1.0 );
       gamma->SetPz( 10.0 ); 
   }
   if ( option3 ) // Option 3: throw particles according to a pT distribution
   {
      // ptDist, etaDist can be a TF1 or TH1
      kine->Dist( Npart, "pi0", ptDist, etaDist );
   }


   // Call Make() on all makers in the chain
   chain->Make();
