  • Update VELO alignment (same alignment for all 2011 data):
    • Module Tx,Ty,Tz,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

  • 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).

  • 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)
