\section{Criteria for the Optimal Signal Extraction (STILL TO DO!!)}

\subsection{Resolution and Bias} 
\ldots {\textit{The jitter to identical input pulses is measured, for times, amplitudes, 
high-gain and low-gain pulses and different signal and background levels }}

\subsection{Stability}
\ldots {\textit The stability of an extractor to slightly varying pulse shapes is examined. }

\subsection{Linearity}
\ldots {\textit The Nuria plots ... }

\subsection{Treatment of Calibration Pulses}

\subsection{Low Gain Extraction}
\ldots {\textit The stability of the low-gain extraction w.r.t. the high-gain extraction}

\subsection{Applicability for Different Sampling Speeds / No Pulse Shaping.}
The current read-out system of the MAGIC telescope \cite{Magic-DAQ} with 300 MSamples/s is relatively slow compared to the fast pulses of about 2 ns FWHM of Cherenkov pulses. To acquire the pulse shape an artificial pulse shaping to about 6.5 ns FWHM is used. Thereby also more LONS is integrated that acts as noise. 

For 2 ns FWHM fast pulses a 2 GSamples/s FADC provides at least 4 sampling points. This permits a reasonable reconstruction of the pulse shape. First prototype tests with fast digitization systems for MAGIC have been successfully conducted \cite{GSamlesFADC}. The signals have been reconstructed within the common MAGIC Mars software framework.

\subsection{Cosmics Data?}
The results of this subsection are based on the following runs taken
on the 21st of September 2004.
\begin{itemize}
\item{Run 39000}: OffCrab11 at 19.1 degrees zenith angle and 106.2
azimuth.
\item{Run 39182}: CrabNebula at 19.0 degrees zenith angle and 106.0 azimuth.
\end{itemize}
