QA-1 for run11 Au+Au 200 GeV 2015-07-26
For Dijet analysis using run11 Au+Au 200 GeV data.
Event, TPC tracks and BEMC hits ADC should be studied.
Here event & BEMC ADC are studied.

Dataset:
Au+Au 200 GeV run11
trigger:
NPE_18 (350503, 350513)
Centrality 0-20% from StRefMultCorrr
QA plots:
The dashed red line is the average value. The solid red line is the average value +/- 3*sigma.
When calculate the average & sigma, the bin with zero content is also counted.
The x-axis is ordered by runid. Each point is for one run. The y-axis is identfied by the histogram label and section title.

10. Follow Kevin Adkins's tight hot tower finding (recursively search for tower has counts > 20% than average after hot one removed, counts for energy > 2GeV hit)
