Structure of WG and tasks of teams• T1: Simulation of key experiments
• T2: Data base for detector parameters• T3: Data storage and access• T4: Online analysis and monitoring• T5: Offline analysis
Scope of the meeting• Exchange of ideas• Definition of tasks and teams, identification of
possible team leaders. The final organization will be decided at next AMB meeting
• Concrete plans on how to proceed should be presented to the AGATA community at the first
