2010.01.18 EEMC response 2006 vs. 2009: typo in TPC volume size bug fix

Click here for previous study before TPC typo fix

Monte-Carlo setup

  • Throwing one photon per event
  • Full STAR y2006h/y2009a configurations
  • Throw particles flat in eta (1.08, 2.0), phi (0, 2pi), and energy (5-35 GeV)
  • Using A2Emaker to get reconstructed Tower/SMD energy (no EEMC SlowSimulator in chain)
  • Vertex z=0
  • ~50K/per particle type
  • Non-zero energy: 3 sigma above pedestal

Before and after the fix comparison

Geometry configurations:

  • y6h:10KeV:old (red) - y2006h with emc_10KeV option
  • y6h:10KeV (black) - y2006h with emc_10KeV option, after TPC typo fixed

y2006h vs. y2009a comparison after a TPC typo fix

Geometry configurations:

  • y9a:10KeV (red) - y2009a with emc_10KeV option
  • y6h:10KeV (black) - y2006h with emc_10KeV option
