Centrality dependence of (a) $N_{\rm part}\Delta\gamma^{112}$ and (b) $N_{\rm part}\Delta\gamma^{132}$ in comparison with the corresponding ESS results using four analysis recipes in Au+Au collisions at $\sqrt{s_{NN}} =19.6$ GeV. The vertical bars denote the statistical uncertainties, the shaded boxes represent the systematic uncertainties, and brackets are uncertainties associated with $N_{\rm part}$. The horizontal dashed lines denote constant fits to $N_{\rm part}\Delta\gamma^{112}_{\rm ESS}$ (or $N_{\rm part}\Delta\gamma^{132}_{\rm ESS}$) over the 20\%--50\% centrality region.
