\section{Optical photons}
Normaly the simulation of ``detected signal'' stops at the level of the deposited energy in
a sensitive volume (e.g.\ in a scintilator tile). However, in some special cases, one would
like to know how the light is propagated through the scintillators. In such case simulation
of optical photons is possible. It will, however, significantly (in some cases dramatically)
reduce the speed of the simulation. The output of the optical photon simulation is stored
in variables starting with the string ``odet\_''. The user has to specify several parameters
in order to simulate optical photons:
%
\begin{description}
\item{\bf /musr/command G4OpticalPhotons \emph{true}}\\
Specifies to musrSim whether optical photons should be simulated or not.
If this parameter is set to \emph{false}, anything connected with optical photons
will be ignored internally in musrSim, and the user therefore does not have to
comment out other parameters connected with optical photons in the macro file.
\item{\bf /musr/command materialPropertiesTable \emph{MPT\_name} \emph{property} \emph{n} \emph{val(1)} ... \emph{val(n)} \emph{E(1)} ... \emph{E(n)} \\
Defines some optical \emph{property} of a given material (e.g.\ absorption lenght,
refractive index, scintillation yield, ...} to a material property table.
\emph{MPT\_name} stands for the material property table name. The table has
\emph{n} different values \emph{val(1)} ... \emph{val(n)} for the same number
of optical photon energies \emph{E(1)} ... \emph{E(n)} expressed in MeV.
If \emph{n}=0, the \emph{property} is called ``constant property''.
Possible \emph{property} keywords are: ABSLENGTH, RINDEX, FASTCOMPONENT, SLOWCOMPONENT,
SCINTILLATIONYIELD, and constant \emph{properties} are SCINTILLATIONYIELD, RESOLUTIONSCALE,
FASTTIMECONSTANT, SLOWTIMECONSTANT, and YIELDRATIO.
\item {\bf /musr/command setMaterialPropertiesTable \emph{MPT\_name} \emph{material\_name}} \\
Assigns a material property table defined by ``/musr/command materialPropertiesTable''
to a given material.
