Class I3ParticleBuilder

java.lang.Object
  iceCube.uhe.analysis.I3ParticleBuilder

public class I3ParticleBuilder
extends java.lang.Object

Build IceCube event(s) reading from the f2k data via standard input. By this way, You can leave the IceTray/i3 file framwork into the pure java world. The built I3Particle objects are outputed via outputStream. Orignally written by S. Yoshida for the IceCube EHE analysis

Constructor Detail

I3ParticleBuilder

public I3ParticleBuilder(boolean isMCTruth)

Constructor. You are forced to choose MC or real data mode.

Method Detail

setRangeOfMCSpectrum

public void setRangeOfMCSpectrum(double logEnergyMinimum,
                                 double logEnergyMaximum)

Set range of MC primary spectrum dN/dE

       double logEnergyMinimum :  log(Energy Minimum [GeV]) in the spectral range
       double logEnergyMaximum :  log(Energy Maximum [GeV]) in the spectral range
       

fillMCPrimarySpectrumWeight

public void fillMCPrimarySpectrumWeight(double powerLaw)

decide if you fills the MC spectrum weight with the dN/dLogE of the MC data. If true, then the method process() calls I3ParticleAnalysisFactor.getDNDLogE() and fills the MC weight with the retuned value

        double powerLaw    :   dN/dE = E**(-powerLaw)
        

fillNeutrinoWeight

public void fillNeutrinoWeight(InteractionsMatrix nuCCmtx,
                               InteractionsMatrix nuNCmtx)

You must call this method if the primary is a (interaction-weighted) neutrino. Then MCPrimarySpectrum weight is convoluted with the interaction weight. You have to call fillMCPrimarySpectrumWeight() a priori. InteractionsMatrix of NeutrinoCharge and NeutrinoNeutral objects in the interaction package (iceCube.uhe.interactions) are set for calculating the relevant cross section.

corsikaMMC

public void corsikaMMC()

Call this method before executing process() when you read out the Corsika-mmc track primary.

process

public void process(java.io.DataInputStream in,
                    java.io.OutputStream out,
                    boolean isFullData)
             throws java.io.IOException

the method to build I3Particle objects with data from the DataInputStream. Generated I3Particle objects are serialized and written out to OutputStream.

Throws:

java.io.IOException

generateI3Particle

protected I3Particle generateI3Particle(int flavor,
                                        int doublet,
