1. Run selection: 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: R10087001 - R10103046
     • skip runs w/ badly functioning TPC (~no vertices found) : R10084013, R10088103, R10081024, R10095032, R10085022, R10088060, R10085103, R10087007, R10093049, R10085118
2. 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
3. Trigger bits requirement

   1. Wiki Markup
      BHT3 trig ID: 23054\[01\] or small IDs for some runs

   2. Wiki Markup
      L2W trig ID: 23060\[01\] or small IDs

   3. L2-bit1: ET>13 GeV
   4. count L2-bit0 (random accept of BHT3) for absolute 'seen' cross section
4. Reco prim vertex requirements
   1. rank>=0
   2. | z-vertex | <80 cm
5. Reco TPC track requirements
   1. prim tracks belong to selected prim vertex
   2. flag=301 for primary or =101 for global component
   3. nFit/nPoss>0.51
   4. for high energy electron candidate require additional
      1. nFitPoints>20 ??
      2. if track PT>10 GeV/c assume it is 10 GeV/c
      3. drop track if the last point on the track belongs to one of the 'worse' 3 sectors:

         • Wiki Markup
           West TPC sector 11, phi =~\[1.9,2.3\] rad, Z>0

         • Wiki Markup
           West TPC sector 4, phi =~\[-0.7, -0.3\] rad , Z>0

         • Wiki Markup
           East TPC sector 21, phi =~\[-0.7, -0.3\] rad , Z<0

   5. do not use TPC dEdX information for SL09b events
6. BTOW: use ideal gains, actual status tables & pedestals
   1. assume tower is dead if status!=1
   2. assume tower ADC=0 if (rawADC-ped)< 3* sigPed
7. BSMD use Willi's 2009 calibration
   1. use relative gains, DB flavor=Wbose
   2. use status bits from DB , flavor=ofl
   3. use pedestal residua from DB , flavor=ofl

   4. Wiki Markup
      assume strip is dead if status not in range \[1,......???] ???

   5. assume strip ADC=0 if (ZS ADC-pedRes)< 3* sigPed
   6. for the record: must use custom absolute calibration ( ADC--> energy), describe it
