void StFastGlauberMcMaker::DoHardCoreSmearing ( )

Finish maker.

Hard-core smearing by sigmaNN

Turn off Gaussian smearing

Definition at line 1239 of file StFastGlauberMcMaker.cxx.

Int_t StFastGlauberMcMaker::Make ( )

Clear all data members

Impact parameter

Generate nucleon positions (r,theta,phi)
Smearing nucleon positions if switch is ON (either DoHardCoreSmearing() or DoGaussianSmearing())
Distribute (r,theta,phi) with repulsion distance ds if ds != 0

Determine impact parameter for each nucleus

No repulsion, just store (r,theta,phi)

Store first nucleon, and increment total

Check all the nucleons stored whether there are overlap each other defined by mRepulsionDistance. If any nucleons overlap, then discard current nucleon and try again

Determine Number of collisions by looping over all pair of nucleons

Need at least one Ncoll

Determine Npart Calculate <x>, <y>, <x^2>, <y^2>, <xy>, ecc_{RP} and ecc_{PP}
