  1. Status of Run Selection THIS TALK IS UNDER CONSTRUCTION Using also p13.06 Post-shutdown data: Runs from 172400 to 176843 (11 May)  55 pb-1 reconstructed Study presented here is a sample of this dataset. Compare with pre-shutdown data G. Bernardi LPNHE - Paris

  2. METB (“no”CH) vs METC (withCH) Pre-shutdown one entry/run. METC-x METB-y Mean MET-x METB is much more stable than METC. Main effect is removal of CH. P13.04 – P13.06 data METC-y METB-y Mean MET-y G. Bernardi LPNHE - Paris

  3. METB and SETB (mean, RMS) Pre-shutdown one entry/run. METC METB SETC SETB G. Bernardi LPNHE - Paris

  4. METx and y, < > and RMS Pre-shutdown one entry/run. RMS-MET-x <MET-x> RMS-MET-y <MET-y> G. Bernardi LPNHE - Paris

  5. Variables for Run Selection Pre-shutdown one entry/run. G. Bernardi LPNHE - Paris

  6. Good Run Definition Only Runs with >= 1000 events are considered. (451 runs, p13.04/05) RUNS from 162004 to 170374 Define the average shift: MET-xy = sqrt [ (<MET-x>)2 +(<MET-y>)2] For a GOOD RUN: 1) Require MET-xy < 3 GeV 2) Require mean scalar ET between > 80 GeV. 3) Require stable RMS of METx and y (< 11 GeV in average)  RUN SELECTION released last week. With full statistics, use MET-xy < 5 GeV in all files of a run, and MET-xy < 3.5 GeV in average. RMS-xy < 16 GeV in all files of a run RMS-xy < 15 GeV in average. G. Bernardi LPNHE - Paris

  7. Summary New run selection on the way. On the post-shutdow data, we see a slight degradation of the calo quantities, not a dramatic effect except in the range 176568 - 176591 We have about 55 pb-1 recoed / available after shutdown. More studies needed. Next update, will be announced to the jetmet & CAT mailing lists. . G. Bernardi LPNHE - Paris
