Dear Xingrui, PAs,

It is great to see the isobar global polarization paper getting ready. I 
have a few comments for your consideration:

Fig. 1: Are these only fit lines.  It might be good, if you draw them as 
points. Also make sure X,Y axis are not touching the labels.

Fig. 4-5: In data/model comparison figures, you have four cases Lambda 
and s-quark  scenario for lambda and anti-lambda in different colors, it 
would be good to label the model in a better way or at least mention the 
color coding in the caption.

Azimuthal angle dependence line 332-336: I think we should not discuss 
the STAR preliminary results in a paper. Although it is a pity that we 
don't have P_yc2 from Au+Au published yet.

About P_yc0 and P_yc2, I was wondering is there any motivation for 
showing both of them. The measurements are very nice, I am wondering is 
there any physics we can disentangle with these two values? Or is it 
merely a cross-check.

line 349: Could you remind me which paper or analysis [61] are you 
referring to?

Fig. 9: How do you do the average for 20-50% centrality? I see the 
Xi-via daughter (blue) are consistently larger than zero, while direct 
Xi's (red) are smaller than zero. But when you averaged the pattern 
flipped. Can you double check.
Can we comapre the xi-polarization between isobar and Au+Au, although 
the error bar may not allow but I was wondering where they stand, 
especially Xi-via-daughter?

I would also suggest preparing supplemental data points or figures for 
lambda anti-lambda polarization separately for Ru+Ru and Zr+Zr. This 
would be important for someone outside STAR who don't have access to 
individuals collision species.


I sign-off with these addressed.

Thanks and regards,
Subhash
