Dear Mike and All,
Here is a small supplement to my last presentation: https://drupal.star.bnl.gov/STAR/system/files/paperProposalNonIdSup_18.08.2022.pdf
S2-3. I used equations from Adam Kisiel's publications, where these relationships between two- and single-particle source sizes are presented. For identical particles, the relation between two-particle and single-particle sizes is sqrt(2) factor, so the results of equations are divided by such factor. In the table, there are single-particle sizes calculated using different charge combinations, and on the next slide, you can see a Figure with these values and their uncertainties (shades are systematic ones). The results are compared with pion sizes for the lowest transverse mass bin (kT = [0.15, 0.25]) for two centrality classes 0-5% and 5-10% (my data have one centrality class 0-10%). The width of those strips is a combination of statistical and systematic uncertainties.
S4-5. On these slides, you can find updated energy dependence plots (with log(sqrt(s_NN)) scale).
S6-7. The K*(892) resonance is visible near k* = 0.3 GeV/c. It is not visible on the imaginary part of the C11 component. But on the zoomed C00 and ReC11, there is a peak for unlike sign pairs. It is better visible in mid-central than in central collisions.
S8-9. For the C00 component, I prepared the ratio all/prim, but in the case of the C11 component, there are very small values, and the difference is better than the ratio to see anything.
