Outline
Data quality Bad runs Reasonable runs
This is more about trackers, for tracking see Tue morning

Data quality
Detector hardware status Readout
Reconstruction
- Enabled ?- Data integrity
Time evolution / stability

Bad runs
Flagged manually (with scripts) based on e-log / shifter rating / experts info /run database
– Runs with unrecoverable data are marked as “bad”.– Runs with somewhat lower efficiency that is
measurable are marked as “reasonable”
When one or more readout crates are not included in the run or not in the trigger

SMT more in detail
What makes a run bad?Missing crates.Large scale HV problems.Solenoid
What compromises data quality?Missing VRBs.Threshold screw ups that affect many HDIs.Suspicious examine histos
What does not degrade run quality?Reduced HV on a few HDIs.Disabled HDIs.

How much do we flag bad ?
SMT 2003:
W/LUMI: 1122 runs with 148.60 pb-1NO LUMI: 91 runs with ? pb-1
BAD: 74 runs with 0.89 pb-1GOOD: 0 runs with 0.00 pb-1REASONABLE: 1134 runs with 147.05 pb-1UNKNOWN: 3 runs with 0.64 pb-1SPECIAL: 2 runs with 0.02 pb-1NO INFO: 0 runs with 0.00 pb-1

Conclusions / Comments
In 2003 5% runs are bad (<1 %lumi, ~4%CTT) Flagging BAD at Lumi block level ?
Not manually ! SMT is not worse CFT lost % channels There are a lot of monitoring plots in RecoCert,
does anybody look at them ? Monitoring of stability/time evolution ? Get feedback from physics to detector groups
