Common selection, cuts will be applied to W, Z-analysis and not varied

( unless explicitly stated)

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: R10087001 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 runs
   2. Wiki MarkupL2W 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>=0rank>0
   2. | z-vertex | <80 <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>20 ??nFitPoints>=15
      2. if track PT>10 GeV/c assume it is 10 GeV/cdrop track if the last point on the track belongs to one of the 'worse' 3 sectors: unmigrated-wiki-markup

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

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

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

   6. do NOT 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!=1
   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=ofl
   4. Wiki Markupassume 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
