Member Function Documentation

edist()

Double_t MicroStat::mdweight::edist ( Double_t *  arg, Double_t *  par  )

staticprivate

energy distribution of particle in gas arg[0] = energy/available energy par[0] = number of particles in gas par[1] = mass ratio = massTot/(massTot-mPart)

Definition at line 19 of file mdweight.cpp.

getKEdist()

TF1 * MicroStat::mdweight::getKEdist ( Int_t  N, Double_t  R  )

private

function used to draw random CosTheta values

find/create energy distribution for given number of particles N and mass ratio R.

Definition at line 42 of file mdweight.cpp.

initGenerateEvent()

void MicroStat::mdweight::initGenerateEvent ( KVEvent *  partition )

virtual

Call before generating an event with StatWeight::GenerateEvent using the given partition and available energy

Implements MicroStat::StatWeight.

Examples

MicroStat_example.C, and MicroStat_example2.C.

Definition at line 153 of file mdweight.cpp.

nextparticleGenerateEvent()

void MicroStat::mdweight::nextparticleGenerateEvent ( Int_t  N, KVNucleus *  part  )

virtual

Called by StatWeight::GenerateEvent when adding a particle to the event N is the number of particles still to add including this one

The algorithm was written by Daniel Cussol (LPC Caen, France).

Implements MicroStat::StatWeight.

Definition at line 188 of file mdweight.cpp.

printKElist()

void MicroStat::mdweight::printKElist ( ) const

inline

Definition at line 51 of file mdweight.h.

resetGenerateEvent()

void MicroStat::mdweight::resetGenerateEvent ( )

virtual

Called by StatWeight::GenerateEvent before generating another event using the same partition as the last

Implements MicroStat::StatWeight.

Examples

MicroStat_example.C, and MicroStat_example2.C.

Definition at line 171 of file mdweight.cpp.

SetAnisotropy()

void MicroStat::mdweight::SetAnisotropy ( double  a, double  b  )

inline

Set anisotropy of particle momentum distribution a,b are maximum and minimum of P(cos theta) i.e. P(cos theta = +/-1) = a P(cos theta= 0) = b

Definition at line 38 of file mdweight.h.

SetWeight()

void MicroStat::mdweight::SetWeight ( KVEvent *  e, Double_t  E  )

virtual

Set available energy, E, and calculate statistical weight for this event

Implements MicroStat::StatWeight.
