1. Run selection: use SL09b muDst after BHT3 'notch' problem was fixed, beginGMT= 2009-03-28 12:34:27, comprising ~80% of recorded data
   • F10448 - F10536
   • 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 and 's
   1. access TRG,TPC,BTOW,BSMD
   info
   1. directly directly from muDst containers
   ,
   2. apply calibrations from DB 'by hand'
   (no use a2e makers, point makers, etc)
   1. in analysis code
3. Trigger bits requirement

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

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

   3. L2-bitsbit1: ET>13 GeV accept
4. Reco prim vertex selection requirements
   1. rank>=0
   2. | z-vertex | <80 cm
5. Reco TPC track selection requirements
   1. prim tracks belong to selected prim vertex
   2. flag=301 for primary or 101 for global component
   3. nFit/nPoss>0.51
      1. for electron candidate require additional
      2. nFitPoints>20 ??
      nFit/nPoss>0.51
      1. if track PT>10 GeV/c assume it is 10 GeV/c
      2. drop track if last point belong to one of the 'worse' 3 sectors:

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

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

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

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 tower strip ADC=0 if (rawADCZS ADC-pedpedRes)< 3* sigPed
   6. use custom absolute calibration ( ADC--> energy)
