Sample 1 : Aquadopp Monitor
Sample 2 : Compass Monitor
• 3D ANTARES detector operational with 5 lines; 4 extra lines in the sea waiting to be connected, 12 lines detector completed early 2008
• Slow control records detector status in database
• Biggest tables are about 1 Go / Years / Line
• Monitor GUI are provided but can be easily generated by users
• Several millions of down going events available to study detector behavior in various bioluminescence conditions
• First underwater neutrino candidates reconstructed in the Mediterranean sea
• MC comparison ongoing, physics results expected soon
