public class FactorialMoments
**************************************************************************** Calculations of normalized factorial moments characterizing local multiplicity fluctuations inside a restricted phase space. It can calculate factorial moments (getFM() method) or normalized factorial moment (getNFM() method). The original version with horizontal binning was proposed in: A.Bialas, R.Peschanski, Nucl. Phys. B273 (1986) 703 B308 (1988) 857

public FactorialMoments(int NmaxOrder, int Bins, int step, double Min, double Max)
NmaxOrder
- Maximum order of factorial moments for the calculationsBins
- Defines Max number of bins used to divide the phase space (>1).
The actual number of divisions is step*Bins. Therefore, 10
bins with step=4 means 400 divisions between Min and Maxstep
- used to increase step for divisionsMin
- Min value in XMax
- Max value in XMethod Detail |
