Data quality Bad runs Reasonable runs

This is more about trackers, for tracking see Tue morning

Data quality

Detector hardware status Readout

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.

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
