iceCube.uhe.decay
Class MuDecayYMatrix

java.lang.Object
  iceCube.uhe.decay.MuDecayYMatrix

public class MuDecayYMatrix
extends java.lang.Object

Matrix of the Energy Transfer dN/dLogY by the mu 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 - logEmu. This is more accurate way than simply
calculating dN/dLogEdecay.

The transfer matrix to the nu-mu
is acquired by the method getMuToNuMuDecayMatrix( ),
that to the electron neutrinos by getMuToNuEMatrix( )
that to the other charged leptons such as e by getMuToEDecayMatrix( )
