     46\subsection{Overview of the MC and analysis chain}
     47
     48After a few iterations to improve the programs in speed,
     49reliability, ... there is a sample of available programs
     50to simulate the behaviour of the MAGIC telescope.
     51Due to the big amount of diskspace needed for this simulation
     52it was decided, that not only one program will generate
     53the MAGIC telescope, but a subsequent chain of different
     54programs. In figure \ref{MC_progs} you can see a overview of
     55the existing programs and their connections.

     96\caption{Overview of the existing programs in the MC of
     97MAGIC.}
     98\label{MC_progs}
     99\end{figure}
     100A detailed description of the properties of the different programs can be found
     101in section \ref{sec_exist_progs}.
     102From that diagram you can see the following features of the simulation and
     103analysis chain of MAGIC. 
     104\begin{enumerate}
     105  \item The simulation of Air showers and the simulation of the night sky
     106        background (NSB) is seperated. 
     107
     108  \item The NSB is seperated in two parts, the contribution from the starfield
     109        and from a diffuse part.
     110
     111  \item To speed up the production the starresponse program creates a databases
     112        for stars of different magnitude.
     113
     114  \item The join of air showers and NSB is done in the camera program.
     115
     116  \item The analysis of MC \underline{and} real data will be done with only one program.
     117        This program is called MARS (Magic Analysis and Reconstruction Software).
     118        The output of the camera program from Monte Carlo data and the output of
     119        the MERPP (MERging and PreProcessing) program for the real data are the same.
     120        So there is no need to use different programs for the analysis. The file
     121        generated by this program used the root package from CERN for data storage.
     122\end{enumerate}
     123In this section we will only describe the usage of the Monte Carlo programs. The
     124descriptions of the MERPP and MARS can be found somewhere else\footnote{Look on the
     125MAGIC home page for more information.}.
