Data '01

• CTD survey in hall 5 (January '01):

  • From markers on +/-Z flange get rotations and twists: j2-j1=-0.6(1) mrad (00:-4.3) T1=-0.7(2) mrad (00:-0.7) T2=+0.4(1) mrad (00:+0.6)

• Superfit with first 4K cosmics for '01 (HRS gas)

  • Similar change in rotation, need more data for twists
  • Worse resolution (triplets: 200 µm, residuals: 250 µm)
