\section{Requirements to start full GRB observations}

In the previous sessions we described the status and tasks we still plan to do
in order to complete the GRB Alarm System.
Parallel to our system also the different subsystems of the MAGIC telescope have
to implement and test strategies for the GRB survey.

\par

We strongly push the responsible persons of the Drive-, Camera-, AMC- and Central
Control subsystems to fulfill the criteria defined in~\cite{design}. We suggest
to make a one week shift where the experts meet and test the GRB
strategies. In order to avoid good observation time we suggest to make the shift
during a moon period. This shift should take place, in arrangement with the
different subsystem managers, before April this year. The time limitation is
based on the moment when SWIFT will start to work fully automatically and send
alerts in real time to the ground stations.
\par

We present now a list of tasks which are crucial for the GRB survey:

\par

\begin{itemize}
\item {\bf Fast slewing:}\

One of the most important issues is to implement and test the fast slewing capability
of the telescope. Especially the communication between CC and Cosy has still to be implemented for
the case of fast movements.

\item {\bf Use of look-up tables:}\

The use of look-up tables to correct the mirror focus during the movement to the GRB
coordinates is desirable. In the alert situation it is a waste of time if we would have to
close the camera lids and carry out the full laser adjustment (\~5~min) before starting the observation.
The reproducibility of the focus with the use of look-up tables has to be proven.
In case of using lookup-tables during the slewing, it is necessary to change the protocol between the AMC and CC.

\item {\bf Behaviour of the camera during moon:}\

It has to be checked what happens when during the pointing to a GRB position the telescope move over the
moon. It is excluded by the GRB Alert System that a burst closer than 30$\deg$ to the moon will be pointed. 
However, it can happen that during the movement of the telescope the moon will pass the FOV.
In this case the HV of the PMTs will be reduced automatically and will not increase fast enough for the
GRB observation.
