Freeze-Out Parameters in Heavy-Ion Collisions at AGS, SPS, RHIC, and LHC Energies

Dependence on the Fitting Procedure. Comparative study of the thermal parameters (a) , (b) (, , and ), (c) , and (d) radius, plotted versus collision energy, extracted within GCE with 1CFO as the freeze-out scheme in the three cases: both and free, and free, and in the third case and fixed from (2). The fitted parameters are insensitive to the chosen scheme.
