+\subsection{starlight simulation}
+
+Due to the big mirror surface the light from the stars around 
+the position of an expected gamma ray source is contributing to 
+the noise in the camera. We developed a program that allows use
+to simulate the star light together with the generated shower. 
+This program takes all stars in the field of view of the camera
+around chosen sky region. The light of these stars is track up to 
+the camera taking the frequency of the light into account.
+After simulating the response of the photo cathode, we
+get the number of emitted photo electrons per pixel and 
+time.
+These number is used to generate a noise signal for all the pixels. 
+In figure \ref{fig_starresp} the response of the trigger and the 
+FADC system can be seen for one pixel with a star of 
+magnitude $m = 7$.
+These stars are typical, because there will 
+be always one $7^m$ star in the trigger area of the camera.
