iceCube.uhe.decay
Class TauDecayYMatrix

java.lang.Object
  iceCube.uhe.decay.TauDecayYMatrix

public class TauDecayYMatrix
extends java.lang.Object

Matrix of the Energy Transfer dN/dLogY  by the tau decays
    The matrix elements are calculated by the methods supplied
    by the Decay class.

The bin width is defined in the Particle class.

Actually each matrix element dN/dLogYdecay is calculated by the integral,
\int dN/dY dY from logY - 0.5xbinWidth to logY + 0.5*binWidth where
logY = logEdecay - logEtau. This is more accurate way than simply
calculating dN/dLogEdecay.

The transfer matrix to the nu-tau
is acquired by the method getTauToNuTauDecayMatrix( ),
that to the other neutrinos such as nu-e by getTauToNuDecayMatrix( )
that to the other charged leptons such as e by getTauToChargedLeptonDecayMatrix( )
while the decay into hadrons
is obtained by getTauToHadronsDecayMatrix( ).
