- 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
- run analysis on muDst's
- access TRG,TPC,BTOW,BSMD directly from muDst containers
- apply calibrations from DB 'by hand' in analysis code
- Trigger bits requirement
Wiki Markup BHT3 trig ID: 23054\[01\] or small IDs for some runs
Wiki Markup L2W trig ID: 23060\[01\] or small IDs
- L2-bit1: ET>13 GeV
- count L2-bit0 (random accept of BHT3) for absolute 'seen' cross section
- Reco prim vertex requirements
- rank>=0
- | z-vertex | <80 cm
- Reco TPC track requirements
- prim tracks belong to selected prim vertex
- flag=301 for primary or =101 for global component
- nFit/nPoss>0.51
- for high energy electron candidate require additional
- nFitPoints>20 ??
- if track PT>10 GeV/c assume it is 10 GeV/c
- 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
- do NOT not use TPC dEdX information for SL09b events
- BTOW: use ideal gains, actual status tables & pedestals
- assume tower is dead if status!=1
- assume tower ADC=0 if (rawADC-ped)< 3* sigPed
- BSMD use Willi's 2009 calibration
- use relative gains, DB flavor=Wbose
- use status bits from DB , flavor=ofl
- use pedestal residua from DB , flavor=ofl
Wiki Markup assume strip is dead if status not in range \[1,......???] ???
- assume strip ADC=0 if (ZS ADC-pedRes)< 3* sigPed
- for the record: must use custom absolute calibration ( ADC--> energy), describe it
