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
