 \section{Results}
 
 \subsection{Trigger studies}
 
+The MC data produced are used to calculate some important
+parameter of the MAGIC telescope on the level of the 
+trigger system. 
+The trigger system build up will consist of different 
+trigger levels. The discriminator of each channel is called the 
+zero-level-trigger. For a given signal each discriminator will 
+produce a digital output signal of a given length. So the important
+parameters of such an system are the threshold of each discriminator
+and the length of the digital output. 
+
+The first-level-trigger is looking in the digital output of the 
+271 pixels of the trigger system for next neighbor (NN) conditions.  
+The adjustable settings on the first-level-trigger 
+are the mulitiplicity, the topology and the minimum required 
+overlapping time. 
+
+The second-level-trigger of the MAGIC telescope will be a 
+pattern-recognition method. This part is still in the design 
+phase. All results presented here are based on studies of the
+first-level-trigger.
