Various rojection of BTOW gains from slopes

  • Method: fit slope for ADC-ped in [15,45]
  • Input: 1M minB events (from L2), days 89-93
  • Example of spectrum
    BTOW softID=20 Endcap tower at similar location
    Results: slopes are on Y-axis
    * eta bins [1,40] map eta range [-1,1]
    * sectors 1-12 maps 12 TPC sectors
    Table with slopes, script used fitBtowSlopes.C

 My observations

  •  plot 2: eta=-1 is lower than eta=+1

  •  plot 3: there is significant # of outliers +/- 20%
