evaluation of new SC & GL for run pp500 in SL10j
As of yesterday (Nov 9 2010) new SC & GL are available
http://www.star.bnl.gov/HyperNews-star/protected/get/startpc/702.html
Samples of 540 run from pp500 run 9 have been run through BFC in SL10j using the chain:
"DbV20101110 OGGVoltErr pp2009c ITTF VFPPVnoCTB BEmcChkStat beamLine Corr4 OSpaceZ2 OGridLeak3D -dstout -evout"
Events passing L2W-trigger have been selected, for all prim vertices the valid TPC tracks with PT>1 GeV/c were selected. For every track the global track component was taken and the average chi2/dof was accumulated per run. ( float globChi2dof=glTr->chi2(); )
Fig 1 shows 1D & 2D distribution of chi2/dof for all runs and all tracks
Fig 2 shows 1D chi2/dof for tracks reco in he East TPC
Fig 3 shows 1D chi2/dof for tracks reco in he West TPC
