Resolutions for single muons

Simulation:

• single muons
• 5 samples of 20 0000 muons in each: pT = 1, 5, 20, 100, 500 GeV
• pseudo-rapidity between -2.5 and 2.5
• vertex spread along both r-phi and z axis (sigma={15um,15um,5.6cm})
• full GEANT
• geometry and digitization: 96_12 (Last modif in /afs/cern.ch/atlas/offline/test/user/g: 13/12/96 12:15)

Reconstruction with PIXLREC:

• standard inefficiencies and noises
• clustering scheme for pixels: r-phi+Z
• three tracking schemes:
  1. PixlRec
  2. PixlRec + local Kalman-filter
  3. PixlRec + local Kalman-filter + TRT
