• Update the TT/IT/OT alignment
  • TT modules Tx, Rz, layers Tz.
  • IT boxes Tx, Tz, Rz
  • OT C-frame Tx, Rz, C-frame layers Tz, modules Tx, Rz.
• Update VELO alignment (same alignment for all 2011 data):
  • Module Tx,Ty,Rz
  • Sensors Tx, Ty
  • 2 halves Tx,Ty,Tz,Rx,Ry,Rz
• Alignment for 2011 reprocessed data
• Alignment set after each magnet polarity and/or technical stop
• IOVs:

• same dof as previous alignment for IT/TT/OT including also the y alignment for full 2011
  • TT modules Tx, Rz
  • IT modules Tx, Rz, boxes Tx, Tz, Rz
  • OT modules Tx, Rz, C-frame layers Tz
  • TT is fixed in its nominal z position and so is OT3-1.
  • Ty for TT/IT/OT
• constants for 4 different IOVs for all 2011 data till the end of August
• data taken from September use the same alignment as the one in July/August period
• IOV: [2011-03-01 - 2011-03-28 - 2011-05-11 - 2011-07-08 - inf).
• Runs [ 87219 - 88182/89333 - 90763/91556 - 94386/95929 -104414]

• include new sensor and module alignment and 2 half alignment strongly reduces the weak mode
• no alignment for Tz at module or sensor level (fix to the metrology)
