Class EventMonoEnergyFlux

java.lang.Object

iceCube.uhe.event.EventMonoEnergyFlux

public class EventMonoEnergyFlux
extends java.lang.Object

This class calculates differential flux dF/dLogE [/cm^2 sec sr] of muons/taus as a function of emg/hadron cascade energy deposited in the detector volume expected from a neutrino flux with monochromatic energy E^2dF/dE = 10^-9 GeV/cm^2 sec sr. The differential flux of mu/tau's which enter into the detector volume after propagating in the earth is apriori given by PropagationMatrix.java in the propagation package and the results are readout from the Data Input Stream which is given when the method readMatrix(in) is called. The cascade energy distribution is given by EventMatrix.class in the Event package. This class is used for neutrino aperture estimation.

EventMonoEnergyFlux

public EventMonoEnergyFlux(java.io.DataInputStream eventIn)
                    throws java.io.IOException

Constructor. Array for propagationMatrix and EventMatrix classes are generated. Note th objects still needs to read the matix file to perform any futher calculation. This can be done by calling the methods readMatrix(DataInputStream in).

Throws:

java.io.IOException
