Hi Katarzyna and Daniel,

The preliminary proposal looks good to me. I have two small questions, probably naïve.

1) Your 2016 topological reconstruction cuts are centrality-dependent but your analysis is for the full 0-80% range. Do you just average the values from the 5 different ranges, or do you perform the analysis in these 5 separate ranges and then add them all together?

2) I think Yi asked this in a meeting once, but I can’t remember the answer: why do you have a large uncertainty from the side-band background selection variation for Delta-phi of 0.31, but zero contribution to the other four? Seems strange to me.

Thanks!

Dear Katarzyna and Daniel,

Thanks a lot for the prompt reply. Looking forward to seeing the updated request. 

Cheers,

Yi

Dear Yi,

In addition to Katarzyna's response: we can estimate how much data we
would need to observed a correlation signal in Au+Au, assuming the same
reconstruction efficiency and a given level of stat. precision (for
example 0.2).

Best regards,
Daniel
