Further information related to this request

  1. Lidia added "y2006h" tag (latest Endcap geometry fixes, and Calorimeters with LOW_EM cuts)
    http://www.star.bnl.gov/HyperNews-star/protected/get/starsimu/452/1.html
     
  2. x/y beam offset:
    Run 6: x=0.0cm, y=-0.3cm (from /STAR/comp/calib/Beamline/Run6)
    Run 9: x=0.3cm, y= 0.0cm (from /STAR/comp/calib/BeamLine/Run9)
     
  3. Vertex z cut:
        +/- 120cm
     
  4. Vertex z spread:
        Run 6: 55cm (gaus fit to Fig.1 from this post: /STAR/node/13276)
        Run 9: 63cm are taken from Pibero's embedding study:
        www4.rcf.bnl.gov/~pibero/spin/dijets/2009.10.23/embedding.html
     
  5. Vertex x/y spread set to zero for all runs.
    FYI, Run 9 x/y spread is x=0.57, y=0.58
        http://www4.rcf.bnl.gov/~pibero/spin/dijets/2009.10.23/XYVertexJetTriggers.png
     
  6. Vertex option:
        Use option consistent with bfc tags used for data production (VFPPV/Run-6 or VFPPVnoCTB/Run-9):
           Run 6: Leave vertex to be reconstructed vertex, and use VFPPV with beamline
           Run 9: Leave vertex to be reconstructed vertex, and use VFPPVnoCTB with beamline

    FYI: bfc options for different years:
    http://www.star.bnl.gov/devcgi/dbProdOptionRetrv.pl
     
  7. Use the latest available "SLXXy" library tag
     
  8. No sdt option for bfc with Monte-Carlo. See note from Jreome's:
    http://www.star.bnl.gov/HyperNews-star/protected/get/starsoft/7905/1/1/2.html
     
  9. Need to add new bfc tag. Request send to starsimu list:
    http://www.star.bnl.gov/HyperNews-star/protected/get/starsimu/453.html
     
  10. Using Perugia0 tunes (i.e. call pytune(320))
