STAR QA Board

["Van Buren, Gene" <gene@bnl.gov>]

Hi, all

A follow-up on the item that Ashish noted 6 runs as having notably different <DCA> on slides 7 & 9 (21238004-009). His plot, vs. run index, is attached below.

I'm also attaching a plot from the Offline QA automatic reference comparison ("AutoQA") of the quantitative result of the Kolmogorov comparisons of the signed DCA distribution to a fixed reference, versus time the data was acquired [GMT]. One should observe a change in this value if the comparison to a reference changes notably. These runs were taken at roughly 2020-08-25 06:00 GMT, plus or minus an hour, which is ~5/8ths of the way from the left edge of this plot to the right edge. One can see that anything going on with the signed DCA at that time wasn't notable compared to other variations in the signed DCA.

So, like Ben, I'm not spotting anything extraordinary for these 6 runs, and I'm even looking at the DCAs.

Ashsih, maybe you can point us to the code you use to determine the <DCA>.

Thanks,

-Gene
