QA part II (Low Luminosity)

I have analysed the  "Low Luminosity"  production P08ic  (without any cuts) that was just produced with SVT+SSD+TPC and TPC only:

 

Hadronization/Underlying Event Systematic for 2005+2006 jet aLL Part II

In Part I of this blog I discussed the porting of the Hadronization and Underlying Event stand-alone pythia code, originally written by Mike Miller, to RCF and the various tests used to determine t

Improving the Isolation Cut

Abstract:  Our goal is to improve the isolation cut by
  1. Reducing the size of the tower cluster
  2. Correcting for energy leakage into neighboring towers
which will (1) decrease the likelyhood that the 2nd photon from a meson decay contributes energy to the gamma candidate, and (2) reduces the amount of energy which the gamma candidate contributes to the isolation energy sum.

DB entry changes between 20080412 and 20080418, preparation for Year8 production

Here is the (reshaped) dump of the db differences (image rescaled, view image for details).

StGammaMaker Status/Issues

Abstract:  A quick summary of the status of the StGammaMaker software, and issues related to producing a large MC event sample.

Run 7 QA

I have analyzed the new test production for run 7 Au+Au @ 200GeV P08ic and compared to the old problematic production P08ib(already deleted by now).I also compared the new production P08ic to the o

On stability of my SMD clustering

 There were valid questions raised about how well the output of my clustering method in the SMD matched in MC and in data.
