Muon_L2 Postmortem in Run 1

Paul Quintas ( .html by J. Linnemann)

What Did We Do Well?

• Ran online approximately = offline without many major physics problems
• Effeciency/Rejection good
  • most triggers were L1, not L2 limited
• Successfully added options CAL_CONF, L2_SCINT
• Successfully incorporated two major MUON_UTIL rewrites
• There are D0 notes which document MUON_L2 history including changes, bugs, dates, etc.

What Could Have Been Done Better?

• More, varied data sets for verification
• 1-2 full-time people working on efficiency/rejection
• No Playback--a large class of muon bugs could not be reproduced offline
