Query: Centrality dependence of chemical freeze-out parameters from net-proton
  and net-charge fluctuations using hadron resonance gas model   We estimate chemical freeze-out parameters in HRG and EVHRG model by fitting
the experimental information of net-proton and net-charge fluctuations measured
in Au + Au collisions by the STAR collaboration at RHIC. We observe that
chemical freeze-out parameters obtained from lower and higher order
fluctuations are though almost same for $\sqrt{s_{NN}} > 27$ GeV, tend to
deviate from each other at lower $\sqrt{s_{NN}}$. Moreover, these separations
increase with decrease of $\sqrt{s_{NN}}$ and for a fixed $\sqrt{s_{NN}}$
increase towards central collisions. Furthermore, we observe an approximate
scaling behaviour of $(\mu_B/T)/(\mu_B/T)_{central}$ with
$(N_{part})/(N_{part})_{central}$ for the parameters estimated from lower order
fluctuations for 11.5 GeV $\le \sqrt{s_{NN}} \le$ 200 GeV. Scaling is violated
for the parameters estimated from higher order fluctuations for $\sqrt{s_{NN}}=
11.5$ and 19.6 GeV. It is observed that the chemical freeze-out parameter,
which can describe $\sigma^2/M$ of net-proton very well in all energies and
centralities, can not describe the $s\sigma$ equally well and vice versa.
