##            the JETMET Run Selection

** ****Missing E****T ****definitions / Criteria **
** ****Results for p13.06 Post-shutdown data:**
** ****Runs from 172400 to 177830 (June 8****th****)**
**                    ********  ****64 pb****-1 **** reconstructed**** **
** ****Compare with pre-shutdown data**
**   ******** ****Total lumi : 115 pb****-1**
** ****Prospects**

##  Criteria to select good runs?

*** Criteria  must be:**
**     ****Physics independent**
**	****Lumi independent**
**	****Robust**
*** Inclusive Criteria  (MET oriented):**
**Average missing E****T ****  (x and y component) ******** must be centered to 0**
**Rms of missing E****T **** is dependent on process/lumi but is slowly varying**
**Scalar E****T **** is not constrained ******** must be used only with caution**
*** Exclusive Criteria (JET oriented) **
**Phi distribution of the Jets must be flat**
**Jet 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**

## MET-x and y, < > and RMS

**Pre-shutdown         ****one entry/run**
** ****RMS-MET-x **
** ****<MET-x>**
** ****RMS-MET-y **
** ****<MET-y>**

##  Good Run Definition

**Only 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 E****T****  > 70 GeV in all files of a run  ****                                         ****	****           and  scalar E****T **** > 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  degradation of the calo quantities. **
**Higher fraction of events at high MET, warm zones**
**We have about 64 pb****-1**** recoed / 57 pb****-1**** good runs in average are  available after shutdown,       i.e.  ****91% of the data**
**This fraction is being increased by making the run selection file by file, or lumi block based**
**          ****but we must correct the caldata chunk**
