STAR QA Board

[Isaac Mooney <fs3383@wayne.edu>]

Hi Raghav,

I’m not sure it’s actually one or two hot towers as you say. This is the same behavior we’ve been seeing since at least last year’s OO run. Rather than one or two hot towers, I think it’s actually probably entire “warm” crates. See https://drupal.star.bnl.gov/STAR/system/files/run21_centralOO_200GeV_QA_JetCorr_PWG_report_May21.pdf s. 27-8 (and for context, s. 21-3). I didn’t explicitly do that same check again for this year’s run, but I don’t expect that the logic would change. But it is something Tong or Veronica could check again if you’re not convinced.

Thanks,

Isaac

Hi Veronica. 

Thanks for the clarification. I think it makes sense now. It would be good see if we can somehow reject the masked towers when we look at full jets (which is the cause of that big bump at 30 something GeV). 

Cheers

Hi Raghav,

I have the QA code running on RACF, but Tong said that he will look into the FCS data as you requested.

My language concerning the charged jets was quite unclear... For days 03-13 (Isaac's plots for these are shown below), there is a lower charged jet population at positive phi due to TPC holes. This charged jet eta-phi seems slightly improved in days 10-20 (just by eye), and this is consistent with improved track quality around/after day 015. Please let me know if you have different or other observations/conclusions from these.

Hi Raghav,

I have just started doing the QA and I am still working out some issues to get it to run on RACF, so Isaac produced the actual QA output files for me this week. I took it a bit easy this weekend and only worked during my shift hours, but I made the QA plots (just using the macro) and put them in slides with info after cross-checking the shift log.

No worries at all. 

I actually did not present on Friday because the plots were not finalized since I was not prepared, so we did not discuss the charged jet eta-phi. It does seem that there is an additional ch jet hot spot next to the one we saw last week, but some of the holes have now been filled in.

I’m not sure i understand what you mean by ’some of the holes have now been filled in’. Could you elaborate? 

I am working with Isaac to get the QA running on my end and then I will work on this request for this specific 890210 trigger for runs 22351048 - 23019026. I appreciate your feedback and I will let you know when I make some progress.

Thanks! sounds like a good plan.

Thanks very much for checking this Veronica! 

From the jetcorr POV, we have a primary interest in the dataset with the trigger id 890210 between the runs 22351048 - 23019026. 

Is it possible to check the QA plots for this particular trigger selection?

Sorry i missed last week’s QA board meeting, but was there any discussion on the funny distribution of the eta-phi map of the charged jets? there seems to be two hot spots in the top right panel in figure 12. For the full jets i can see its dominated one one or two hot towers. 

I have a request regarding the QA for this particular trigger 890210, we requested that the FCS be included in the data stream, so is it possible to include QA on that as well? Thanks! 

Cheers

Hi all,

I have put together slides for JetCorr QA for days 010-020 and uploaded them to the Jan 21 meeting page... thank you for your patience!

Please let me know if you have any questions/comments.

Thanks,

Veronica
