STAR QA Board

[Han-sheng Li <li3924@purdue.edu>]

Dear All,

Please find my slides in the following link:

https://drupal.star.bnl.gov/STAR/system/files/QA23_0728.pdf

On slide 3, we think the left plot (day156-169) looks reasonable, while the right (day181-206) looks problematic.

On the left plot, except for the masked-out RDO, the 2D distribution seems quite flat, with only ~20% fluctuations. However, on the right plot, every TPC sector seems to have 50% fluctuations, and different sectors have different fluctuation patterns. This may bring issues to the v2 measurements.

Does anyone have any idea about this eta-phi distribution?
What could be the reason causing the problem? 

Best regards,

Han-Sheng
