Mass vs. Zgg, effect of SPC

Updated on Sun, 2019-03-10 15:17. Originally created by ckimstar on 2019-03-05 17:21.

- Update in Mar. 6:
a. A mroe detailed report is prepared: drupal.star.bnl.gov/STAR/system/files/CKim_FMSCalib_190306.pdf
b. I took a mistake when preparing plots below: right plots actually produced in SPC + Cluster quality cut in OR

//-------------------------------------------------------------------------------------------------------------------

- To test what caused strange structure in " mass > 0.2 + Zgg > 0.5 + small cells " .
* p12 - p13 of drupal.star.bnl.gov/STAR/system/files/CKim_FMSCalib_190121.pdf

- Checked if I can reproduce same plots with existing QA tree
- Then applied single point cluster (SPC) cut on same plots and reproduced
- The strange structure mostly disappeared, however concentration at high Zgg remains - is it a problem?

- Comparison plots from now: wo/ (left) vs. w/ SPC (right) cut
- Everything else is same
