iceCube.uhe.muonModel.CascadeFluctuationFactory

public class CascadeFluctuationFactory
extends java.lang.Object

This class describes the intrinsic flucuation of atmospheric muon energies due to extensive airshower process. The Elbert model that is used in AtmMuonBunfleFlux.java associates muon energies to their primary cosmic ray energy by one on one relation. The CascadeFlucuationFactory simulates their flucuation in hanndy manner using inputs from the Corsika full simulation. AtmMuonBundleFlux can use this factory to calculate the flux taking int account the fluctuation if the option is set.

getProbability

public double getProbability(double logR,
                    double logPrimaryEnergy,
                    boolean asInIce)

Return the probability of Log10((E_muon/E0)/ Bar(E_muon/E0)), a relative depature from the mean of the energy ratio.

    double logR           : log10((E_muon/E0)/ Bar(E_muon/E0))
    double logPrimaryEnergy: log10(Primary Cosmic Ray Energy [GeV])
    boolean asInIce       : true for inIce muon energies, false for those at the earth surface
    

getLogMuOverCREnergyMin

public double getLogMuOverCREnergyMin(double logPrimaryEnergy,
                             boolean asInIce)

Returns minimum of Log((E_muon/E0)/ Bar(E_muon/E0))

getLogMuOverCREnergyMax

public double getLogMuOverCREnergyMax(double logPrimaryEnergy,
                             boolean asInIce)
