QA-1 for run11 Au+Au 200 GeV 2015-07-26

Motivation:

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.

Previous study by Hui Wang on this data for MinBias trigger can be found at:
Run11_200GeV_refMult.pdf , 4_10_2012_PWGC_evo.pdf , 4_3_2012_PWGC_evo.pdf , 3_20_2012_PWGC_evo.pdf , 1_31_2012_evo.pdf.

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.

Event variables:

1. refmult


(All the NPE results shown here is for 0-20% from StRefMultCorr class. For the reference, One plot without centrality cut is listed before
there is less statiscs used in this plot but the trend is the same)
ZDC coincidence rate:

No run out of range.

9. 2-D plot of BEMC ADC vs BEMC tower id

x-axis is the BEMC tower id (total 4800 towers)
y-axis is the BEMC ADC



The NPE 18 trigger ADC is seen as the ADC >~ 200.

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)
