OUTPUT from iteration 2

  1. INPUT ~1.5 M minB events. SMD gains from slopes. 
    Content:
* bullets 2-5 show frequency plots. The point is all noise strips, 
  towers,pre/post tiles are masked out .
* bullets 6-13 show average MIP response averaged over 15 strips
   for every sector & plains.
* bullets 14-16 show comparison of current absolute gains for layer 1,2, and 6.
   Here you see that both ^u & 6V do not follow the pattern.
* bullet 17 shows which strips are served by 6S1 (crate=88) to help make 
  the point that 6S1 may be the cause.
  2. Hit distribution for sector 5
    Left column requires only UxV pattern in SMD, right column also mipT & P > thr & Q > thr & R > thr.
    Top: X vs. Y; middle: accepted U-plain strips; bottom: accepted V-plain strips. ( PS)

  3. Hit distribution for sector 6. ( PS)

  4. Hit distribution for sector 7. The peak @U070 & @V045 is from missing postshower 07RD03. ( PS)

  5. Hit distribution for sector 8. ( PS)

    Absolute current gains for SMD plains

  6. Absolute gain for SMD plain 05U

    * sum reco MIP energy for pair of strips
    * add data from 15 consecutive strips
    * fit Landau, MIP energy [0,5] MeV is on the X-axis.
    The last two plots show distribution of MPV and sigma for Landau fits. Green veritcal line at 1.3 MeV is the goal. ( PS)


    Average MIP response for 05U , blue line at 1.3 MeV is the goal. ( PS)

  7. Absolute gain for SMD plain 05V ( PS)


    Average MIP response for 05V ( PS)

  8. Absolute gain for SMD plain 06U ( PS)


    Average MIP response for 06U ( PS)

  9. Absolute gain for SMD plain 06V ( PS)


    Average MIP response for 06V ( PS)

  10. Absolute gain for SMD plain 07U ( PS)


    Average MIP response for 07U ( PS)

  11. Absolute gain for SMD plain 07V ( PS)


    Average MIP response for 07V ( PS)

  12. Absolute gain for SMD plain 08U ( PS)


    Average MIP response for 08U ( PS)

  13. Absolute gain for SMD plain 08V ( PS)


    Average MIP response for 08V ( PS)

    Comparison of current gains vs. sector & layer

    Spacial position of SMD layers:
    sect 8 sect 7 sect 6 sect 5
    IP Z=0
    Layer 1 U V - U
    Layer 2 V - U V
    Layer 3 - U V -

  14. Overlay of all SMD plains for Layer 1. Pol4 is fitted to each distribution. A common U-shape would describe all 3 sets rather good.

  15. All SMD plains for Layer 2. The 6U plain (in red) is more scattered and has different strip dependence (low strip ID's are lower)

  16. All SMD plains for Layer 3. The 6V plain (in red) has similar shape but magnitude is ~20% lower
