 \subsubsection{Collection area}
 
+The trigger collection area is defined as the integral 
+\begin{equation} 
+  A(E,\Theta)  = \int_{F}{ T(E,\Theta,F) dF}
+\end{equation} 
+where T is the trigger probablity. F is perpendicular to

 \subsubsection{Threshold of MAGIC telescope}
 
+The threshold of the MAGIC telesope is defined as the peak
