  1. Run selection: run list (423 runs) , muDst list (8551 files) , available # of events: input=1.30e6, L2wET=9.65e5
  2. use SL09b muDst after BHT3 'notch' problem was fixed, beginGMT= 2009-03-28 12:34:27, comprising ~80% of recorded data
    • RHIC fill range: F10448 - F10536
    • STAR run range: R10086140 - R10103046
      • skip runs w/ badly functioning TPC (~no vertices found) : R10084013, R10088103, R10081024, R10095032, R10085022, R10088060, R10085103, R10087007, R10093049, R10085118
  3. run analysis on muDst's
    1. access TRG,TPC,BTOW,BSMD directly from muDst containers
    2. apply calibrations from DB 'by hand' in analysis code
  4. Trigger bits requirement
      unmigrated-wiki-markup
    1. BHT3 trig ID: 23054\[01\] or small IDs for some runsunmigrated-wiki-markup
    2. L2W trig ID: 23060\[01\] or small IDs
    3. L2-bit1 (on line value was ET>13 GeV)
    4. count L2-bit0 (random accept of BHT3) for absolute 'seen' cross section
  5. Reco prim vertex requirements
    1. rank>0
    2. | z-vertex | <100 cm
  6. Reco TPC track requirements
    1. prim tracks belong to selected prim vertex
    2. (flag=301 for primary) or (flag=101 for global) component
    3. if primary is valid but its global pointer is NULL skip the primary track, but keep the rest of the event
    4. nFit/nPoss>0.51
    5. for high energy electron candidate require additional
      1. nFitPoints>=15
      2. if track PT>10 GeV/c assume it is 10 GeV/c
    6. do not use TPC dEdX information for SL09b events
  7. BTOW: use ideal gains, actual status tables & pedestals , 'ofl' flavor for all, no time stamp set in the user code
    1. assume tower is dead if status!=1unmigrated-wiki-markup
    2. assume tower ADC=0 if (rawADC-ped)< \ [3*sigPed or 8 counts]
  8. BSMD use Willi's 2009 calibration , no time stamp set in the user code
    1. use relative gains, DB flavor=Wbose
    2. use status bits from DB , flavor=ofl
    3. use pedestal residua from DB , flavor=oflunmigrated-wiki-markup
    4. assume strip is dead if status not in range \ [1,19]
    5. assume strip ADC=0 if (ZS ADC-pedRes)< 3* sigPed
    6. for the record: must use custom absolute calibration ( ADC--> energy), describe it
