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
   • R10087001 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
   1. Wiki MarkupBHT3 trig ID: 23054\[01\] or small IDs Wiki Markupfor some runs
   2. L2W trig L2W trig ID: 23060\[01\] or small IDs
   3. L2-bits: 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 selection requirements
   1. rank>=0rank>0
   2. | z-vertex <80 | <100 cm
6. Reco TPC track selection requirements
   1. prim tracks belong to selected prim vertex
   2. (flag=301 for primary) or (flag=101 for global componentnFitPoints>20 ??) 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>0.51drop track if last point in 'worse' 3 sectors:
   5. West TPC sector 11, phi =1.9,2.3 rad
   6. West TPC sector 4, phi =-0.7, -0.3 rad
   East TPC sector 21, phi =-0.7, -0.3 rad
   7. for high energy electron candidate require additional
      1. nFitPoints>=15
      2. if track PT>10 GeV/c assume it is 10 GeV/c
   8. 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. 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
