Tower slopes day 67
  • HV used : set vi_A
  • 250K minB events, i.e. ~50% of events form minB runs 7067089-93
  • Procedure:
    * rebin(2)
    * find ped
    * fit slope ADC [ped+12, ped+38], all in initial channels despite rebinning
    * report: slope, error, integral

  • PDF with 720 spectra.
    Page1 30 towers @ etaBin=1,
    Page2 another 30 towers @ etaBin=1,
    ...
    Page24 30 towers @ etaBin=12

  • Table with slopes & integrals

  • Distribution of slopes vs. eta bin. (X is the 7-th column in the table)

  • Outliers excluded from the plot
