+The Sgr A$^*$ data that has been taken in September 8, 9 and 10 2004, is
+still being analysed. Preliminary results were presented at the MAGIC
+collaboration meeting in Berlin, 21-25th February 2005.\\
+Up to now there is only 2.9 hours of ON data available at a very large zenith
+angle range. Some details of the data set are shown in table \ref{table:GC_dataset}.\\

+In our preliminary analysis we used the Random Forest method for the gamma
+hadron separation. For this purpose high
+ZA (65$^\circ$ Zd and 205$^\circ$ Az) Monte Carlo gammas were generated, 
+99500 events in all, with energies between 200
+and 30,000 GeV. The slope of the generated spectrum is $-2.6$, conforming the
+energy spectrum of the Crab nebula... 
+
+The MC sample is divided into trainings
+and test sample. Since there is no dedicated OFF data available, we used a
+subsample of Sgr A$^*$ ON data for the Random Forest training. As trainings
+parameters we used SIZE, DIST, WIDTH, LENGTH, CONC, and M3Long...
