2012 Data Alignment

NEW corrected IOVs for 2012 data tag of CondDB XXXXX

  • VELO: same alignment for the whole 2012
    • Module Tx,Ty,Tz,Rz
    • Sensors Tx, Ty
    • 2 halves Tx,Ty,Tz,Rx,Ry,Rz

  • Tracker (IT,TT,OT): different alignment after each magnet polarity change or TS. IOVS summarized in the table below.
    • TT modules Tx, Rz
    • TT modules Tz aligned until 28 August, between 29August and 6 November fixed to the latest alignment, from 7 November fix to the survey
    • TT layer Tz
    • IT layers Tx, Tz aligned until 28 August, between 29 August and 6 November fixed to the latest alignment, from 7 November fix to the survey
    • IT boxes Tx, Tz, Rz
    • OT C-frame Tx, C-frame layers Tz
    • TT is fixed in its nominal z position and so is OT3-1.
