Class EventMatrix

java.lang.Object
  iceCube.uhe.event.EventMatrix

public class EventMatrix
extends java.lang.Object

This object handles a matrix table generated by RunManager.runEventOnMatrix(DataOutputStream out, int numEvent). It gives a dN/dLogEcascade(mu or tau) where Ecascade is a total energy deposit in form of electrons or hadrons initiated by UHE muons or taus running in the detector voluce. Propagation of muons and tauons are treated by Event.java. The matrix table this object reads out is similar with PropagationMatrix.getFtauToHadron(int iLogE,int jLogE) or PropagationMatrix.getFmuToHadron(int iLogE,int jLogE), for example, in the propagation package. A main difference is the PropagationMatrix is calculated by numerically solving the transport equation which is suitable for particle propagation in the Earth over long range while THIS matrix table is calculated by the Monte Carlo method by Event.java which works especially for particle propagation inside the detector volume where the fluctuation of the energy loss profile and total energy deposit from an event do matter.
