Hi Tristan,

This is fine with me for the moment.

Thanks,

Isaac

Hi All,

Given the discussion of the result I'm seeing possibly having a sizable contribution from non-flow effects, I have been asked to update the preliminary figure to reflect this.  I propose calling the measurement v_{2}^{unsubtracted}, as v_{2}^{obs] is already used to describe the v2 obtained before correcting for the event plane resolution.  I have updated the figures and preliminary figure request to reflect this. 

Please let me know if this is acceptable, or if there is other labeling you would prefer I use.

Cheers,
Tristan

Hi Tristan,

Thanks a lot for the preliminary requests. I have some minor comments for your consideration. 
- p9: I would add "average background density" in front of pho is 0. 
- I think we agreed (from the discussion between Rongrong and Rosi) that we will use v2^obs instead of v2 in the result. Could you please change it and update the plots on your poster? 

Cheers,
Yi

Hi All,

I have realized the slides I presented at last Thursday's meeting for the preliminary figure request were never distributed properly.  They can be found here:

I have added a slide showing a comparison to a quick check I added at low pt track v2 compared to results by Shengli Huang who has done a more detailed study of flow measurements in O+O.  I believe the comparison shows reasonable agreement between the results, averaging between the 20-40% and 40-60% bins they show.  

Cheers,
Tristan
