• Tests on memory consumption in p12: Yann Coadou.
  p12.04 shows a memory leak of 8 kB/event. Suspicion currently on l3tCalUnpTool.
  Action item: Marumi to investigate.
• Status of L3Muon and remaining steps to certification: Martin Wegner

Concentrating on L3MuoCentralMatch at the moment.
• Special run missed debug_chunk for L3MuoCentralMatch (Trigsim suggests problem has been fixed.) Trigsim used for studies on the special run.
• Matching in delta_eta and phi of Muon-Track. Compare with offline matching. Quality similar.
• Requiring loose muon eta<1.4: efficiency 42% for offline match, 35% for L3. Is pt cut the same for offline and L3 TRACKS?
• Suggestion of matching problem in L3MuoCentralMatch at phi=2*pi?
• Martin and Daniel will sit together to look at events where offline finds match and L3 doesn't.
• Effect of L3 not knowing solenoid and toroid polarity needs to be evaluated.
• Certification of L3MEt: Markus Klute
• L3MEt tool and two electron + MEt triggers are approved by the Trigger Board.
• Requires p12 to be run online. L3 algorithm tests were presented to the Trigger Board by Marumi Kado. Conclusion: we are ready to run p12 online.
• Monitoring of MEt online stability is now possible (and very important).
• Of the next steps probably the most important is investigating the effect of ignoring coarse hadronic cells on the MEt.
• Status and plans for "Online-offline" comparator: Han Do

Plan is to try to make comparison of physics_results for specific tools, starting with tau. Define "equality" operator for each tool's physics_results. Reasonable tolerance needs to be defined for each quantity.
