Class AtmMuonBundleFitter

java.lang.Object
  iceCube.uhe.analysis.AtmMuonBundleFitter

public class AtmMuonBundleFitter
extends java.lang.Object

This class provides methods to fit I3Particles with the CEL approximated AtmMuonBundle flux. Use AtmMuonBundleFlux.java in the muonModel package to calculate the energy spectrum of muon bundles at the IceCube depth based on the CEL approximation, i.e., AtmMuonBundleFlux.getDFDLogE(logEnergy,cosTheta,beta_loss,slantDepth). See the API document of the JULIeT's muonModel package for the details. Written by S. Yoshida 2007 February 16

Method Detail

fillAtmMuonBundleFluxWeight

public static void fillAtmMuonBundleFluxWeight(I3Particle iceParticle,
                                               ParticlePoint s,
                                               AtmMuonBundleFlux muonFlux)

Fill I3Particle with the Atmospheric Muon Bundle Flux weights. The flux at the IceCube depth is given by the CEL approximated calculation in getDFDLogE(logE,cos(theta),beta,depth) in AtmMuonBundleFlux.

setAtmMuonBundleFlux

public static void setAtmMuonBundleFlux(I3ParticleAnalysisFactory analizer,
                                        ParticlePoint s,
                                        AtmMuonBundleFlux muonFlux)

Set the Atmospheric Muon Bundle flux to all the I3Particles stored in the I3ParticleAnalysisFactory. The set flux is subject to be compared with the real data distribution.

compare

public static IComparisonResult compare(I3ParticleAnalysisFactory mcAnalizer,
                                        I3ParticleAnalysisFactory dataAnalizer,
                                        IHistogramFactory histoFactory)

Make a chi2-based statistical comparison between the MC with the muon bundle flux and the real data

                                        I3ParticleAnalysisFactory mcAnalizer2,
                                        I3ParticleAnalysisFactory dataAnalizer,
                                        IHistogramFactory histoFactory)

Make a chi2-based statistical comparison between the two MCs (one with E**-1, another with E**-2, for example) with the muon bundle flux and the real data
