The following selection, cuts will be applied to W, Z-analysis and not varied unless explicitly stated

  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. Trigger bits

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

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

    3. L2-bits: ET>13 GeV accept
  3. Reco prim vertex selection
    1. rank>=0
    2. | z-vertex | <80 cm
  4. Reco TPC track selection
    1. prim tracks belong to selected prim vertex
    2. flag=301 for primary or 101 for global component
    3. nFitPoints>20 ??
    4. nFit/nPoss>0.51
    5. drop track if last point in 'worse' 3 sectors:

      • West TPC sector 11, phi =[1.9,2.3] rad

      • West TPC sector 4, phi =[-0.7, -0.3] rad

      • East TPC sector 21, phi =[-0.7, -0.3] rad

  • No labels
