 \subsubsection{MMCS - Magic Monte Carlo Simulation} 
-\subsubsection{reflector                          } 
+ 
+This program is based on a CORSIKA simulation. It is used to generate
+air showers for the MAGIC telecope. At the start one run of the 
+program, one has to define the details of the simulation. 
+One can specify the following parameters of an shower 
+(see also figure \ref{pic_shower}): 
+%
+\begin{enumerate}
+  \item the type of the particles in one run ($PartID$)
+  \item the energy range of the particles ($E_1, E_2$) 
+  \item the slope of the Energy spectra 
+  \item the range of the shower core on the ground $r_{core}$. 
+  \item the direction of the shower by setting the range of 
+	zenith angle ($\Theta_1, \Theta_2$) and 
+	azimuth angle  ($\phi_1, \phi_2$)
+\end{enumerate}

+at the begin of an MMCS run.}
+\label{pic_shower} 
+\end{figure} 
+Other parameters, that will be important in the analysis later,
+can be calculated. I.e. the impact parameter $p$ is defined by 
+the direction 
+of the shower ($\Theta, \phi$) and the core position 
+($x_{core}, y_{core}$). 
+
+The program MMCS will track the whole shower development 
+through the atmosphere. All the cerenkov particles that hit a 
+sphere around the telesope (in the figure \ref{pic_shower} 
+drawn as the circle around the telecope position) are stored 
+on disk. It is important to recognize, that up to now no 
+information of the pointing of the telescope was taking into
+account.  
+This cerenkov photons are the input for the next program, 
+called reflector. 
+
+
+\subsubsection{reflector} 
+
+The aim of the reflector program is the 
+tracking of the cerenkov photons to the camera 
+of the MAGIC telescope. So this
+is the point where we introduce a specific pointing of 
+the telescope ($\Theta_{MAGIC}, \phi_{MAGIC}$).
+For all cerenkov photons the program 
+tests if the mirrors are hitten, calculates the 
+probability for the reflection and tracks them to the 
+mirror plane. All the photons that are hitting the 
+camera are written to disk (*.rfl)  
+with their important parameters 
+($x_{camera}, y_{camera}, \lambda, t_{arrival}$). 
+These parameters are the input from the shower simulation
+for the next program in the 
+MC simulation chain, the camera program. 
+
 \subsubsection{camera} 
+
+The camera program simulates the behaviour of the 
+PMTs and the electronic of the trigger and FAC system. 
+For each photon out of the reflector file (*.rfl) the 
+camera program calculates the probability to generate
+an photo electron out of the photo cathode. If a photo
+electrons was ejected, this will create a signal in the 
+trigger and FADC system of the hitted pixel. 
+You have to specify the
+parameter of the signal shaping 
+(shape, Amplitude, FWHM of signal)
+at the beginning of the 
+camera, seperatly for the trigger and the FADC system. 
+All signal from all photoelectrons are superimposed for
+each pixel. As an example you can see the output of 
+the trigger and FADC system in figure \ref{fig_trigger_fadc}. 
+\begin{figure}[h]
+
+ \caption{The response of one shower from the trigger (left) and 
+fadc system (right).}
+\label{fig_trigger_fadc}
+\end{figure}
+
+All these analog signals going into the trigger system are used 
+to check if for a given event a trigger signal was generated or 
+not. But before the start of the camera program on also has to
+set a few parameters of the trigger system like: 
+\begin{itemize}
+  \item diskriminator threshold
+  \item mulitplicity
+  \item topology 
+\end{itemize} 
+With this set of parameter the camera program will analyse
+if one event has triggered. For the triggered event all the FADC
+content will be writen on the file (*.root). In addition all the 
+information about the event ($PartID, E, \Theta$,...) and 
+information of trigger (FirstLevel, SecondLevel, ..) are also 
+be written to the file.
+
+One of the nice features of the camera program is the possiblity
+so simulate the NSB, the diffuse and the star light part of it. 
+But before doing this, on has to start other programs 
+(called starresponse and starfieldadder) that are describe 
+below.
+
+\subsubsection{starresponse}
+
+This program will simulate the analog response for stars of
+a given brightness $B$.
