  We study chemical freeze-out parameters for heavy-ion collisions by
performing two different thermal analyses. We analyze results from thermal fits
for particle yields, as well as, net-charge fluctuations in order to
characterize the chemical freeze-out. The Hadron Resonance Gas (HRG) model is
employed for both methods. By separating the light hadrons from the strange
hadrons in thermal fits, we study the proposed flavor hierarchy. For the
net-charge fluctuations, we calculate the mean-over-variance ratio of the
net-kaon fluctuations in the HRG model at the five highest energies of the RHIC
Beam Energy Scan (BES) for different particle data lists. We compare these
results with recent experimental data from the STAR collaboration in order to
extract sets of chemical freeze-out parameters for each list. We focused on
particle lists which differ largely in the number of resonant states. By doing
so, our analysis determines the effect of the amount of resonances included in
the HRG model on the freeze-out conditions. Our findings have potential impact
on various other models in the field of relativistic heavy-ion collisions.
