-It has been also studied the effect on the trigger rate of the discriminator 
-threshold (see figure \ref{fig_rates}). The trigger rate decreases

+These results show that the MAGIC telesope will use a disriminator
+threshold of about 4 mV. This value corresponds to a threshold of
+about 8 photo electrons. 
+
+It has to be mentioned here, that all the results here are based on 
+the first level trigger. There is a big potiential to optimize the 
+settings here. I.e. the background rate can be reduced by
+increasing the discriminator threshold for a few dedicated pixels,
+that have a star in their field of view. Studies in this direction are
+ongoing and will be presented on the conference. 
 
 \section{Conclusion}
+
+We presented the actual status of Monte Carlo simulation for the MAGIC
+telescope.
