  1. CFT Pedestal versus Tick NumberYi JiangUniversity of Michigan • Data: no-zero-suppression zero-bias run169835 • Use cft_tuple package to deal with 15000 events ( only the channels in crate 50, VRB 9, hdi 4 and crate 51, VRB 9 , hdi 1)

  2. II. The pedestal distribution depends on different tick number: (1)The mean value of pedestal changes around 10~15 ADC countson different tick number. (2) The RMS of pedestal has some structure. III. Channel correlation study: in crate 50, tick=7 channels have double peak pedestal distribution Look at different channel pedestal readout event by event.

  3. Choose: SVX=0, chanID=38, 108 SVX=1, chanID=10, 73, 117 SVX=3, chanID=10, 77, 109 SVX=4, chanID=20, 117 SVX=5, chanID=10, 108 SVX=6, chanID=10, 118 SVX=7, chanID=11 In SVX 0 and 1 channels have correlation in same SVX and different SVX. In other SVX, it hard to say so.
