Hi Zhiwan,

   Thanks for the slides. It is true that many quantities are more stable towards the later runs, but this is also larger than the range you had provided. For embedding we should have a realistic sampling of data that we use in the analysis so that it accurately captures the detector effects. Stable period is not necessarily the priority. Also, indeed there are more runs after 21027007. So we should try to get the full good run list soon.

if Xianglei needs only several good runs for his purpose, he can use your list above 

Best,

Sooraj

Hi Sooraj,

 I checked the different QA variable quality vs runid, and this period is very stable: 

See slide 8-11 of : https://drupal.star.bnl.gov/STAR/system/files/11.5_GeV_QAboard_Zhiwan_v3.pdf

The problem Tommy mentioned is that I found there are more run after 21027007 listed in the run log, which was not included in previous QA check years ago. There should be about 80M more data. So I am reanalyzing the bad run list to include those run period.

 If the embedding data need a stable period, I would recommend from 

21021012 - 21027004
Please also exclude one bad run: 21025042 from the period. 

Kindly let me know if you have any more questions.

Best,

Zhiwan

Hi Zhiwan,

   Why this run period? We have several more days of data taking for 11.5 GeV. For embedding it is important that we get a realistic sampling over the whole run period. If the full bad run list is not ready we should try to get it as soon as possible

Best,

Sooraj

Dear Xianglei,
 For Au+Au 11.5 GeV(run20) please use this run period:
21021012 - 21027004
Please also exclude one bad run: 21025042 from the period.

Kindly let me know if you would need any more information.

Best,
Zhiwan

That list needs to be discussed before it can be made final, and usually a few more runs will be added after the discussion.  However, depending on your purpose and how urgent you need it, it may be good enough.
