3. To-do list 1.Finish copying bad-wire maps from test to production DB2 tables 2.Insert DQ parameters (root s) in HepDB for 2004 3.Clean DB of all test runs 4.Tag and build executable 5.Carefully examine reconstruction UIC file 6.Confirm presence of SIMKBCK parameters in DB 7.Reconfigure kmc queue: 214 B80

4. EmC and DC hits from random events inserted in proportion to L inst EmC hits require careful MC/data timescale alignment Special treatment for “noise” hits on EmC (missing t A or t B ) Background from random triggers –data MC Cluster time distributions ( t 0 from K S secondaries) K S  p 0 p 0, K L crash Overall accidental level MC/data = 1.05 K S  p + p -, K L crash Overall accidental level MC/data = 1.19 Track reconstruction efficiency higher in MC when t 0 incorrect t cl (ns) t cl (ns) ~3% of clusters in tail ( t < 0)
