64 pb-1 reconstructed
• Compare with pre-shutdown data
Total lumi : 115 pb-1

Jet/Met prescriptionsDecember 2002
All analyses based on p13 should NOT use the unclustered energy in the CH (layers 15,16,17)
They should use the CH cells only when they are in towers which are part of a jet satisfying the Jet-Met Criteria
From METC to METB (cf JCCB)
Reduce fake jets using - f90 variable (p13) - new jet seeding (p14)
- T42 (p14?)

METB is much more stable than METC. Main effect is removal of CH.

Criteria to select good runs?* Criteria must be: Physics independent
Lumi independentRobust
* Inclusive Criteria (MET oriented):Average missing ET (x and y component) must be centered to 0Rms of missing ET is dependent on process/lumi but is slowly varyingScalar ET is not constrained must be used only with caution
* Exclusive Criteria (JET oriented) Phi distribution of the Jets must be flatJet multiplicity is physics dependent: stable for a given trigger mix
only the phi uniformity (but it’s already a lot!) can be safely tested w/o making physics assumptions

Good Run DefinitionOnly Runs/Files with >= 1000 events are considered, in order to have
enough statistical precision on the average/rms measurements.
Define the average shift: MET-xy = sqrt [ (<MET-x>)2 +(<MET-y>)2] and similar def. for RMS-xy = sqrt [ ( RMS-x )2 +( RMS-y )2]
To declare a RUN “GOOD”:
1) Require MET-xy < 6 GeV in all files of a run, and MET-xy < 4 GeV in average
2) Require RMS-xy < 18 GeV in all files of a run and RMS-xy < 16 GeV in average
3) Require scalar ET > 70 GeV in all files of a run and scalar ET > 80 GeV

From the logbook:
CAP Marco Verzocchi Inherited store 2507 from the previous shiftcrew. …….At around 4:00 (roughly 3/4 of run 176568) two BLS started misbehaving, giving 4 contiguous hot cells at (eta,phi)= (-31/-32,56/57). This was first noticed by the remote GM shifter, and then it took almost 2 hours to fix it (with help from Nirmalya).
The runs affected by this problem are 176568 (last quarter), 176569 and 176570. After the problem was fixed went back to normal smooth running. There is no explanation for the fact that the two BLS boards started misbehaving almost simultaneously.

Summary
New run selection performed on post-shutdown data
On the post-shutdown data, we see a slight degradation of the calo quantities, not a dramatic effect except in some short ranges 176568 - 176591
We have about 64 pb-1 recoed / 57 pb-1 good runs available after shutdown, i.e. 91% of the data
This fraction can be increased by making the run selection file by file, or lumi block based.
