On Extraction of Chemical Potentials of Quarks from Particle Transverse Momentum Spectra in High Energy Collisions

Table 2

Parameter values corresponding to the solid curves in Figure 1. The relative errors for the effective temperatures and ratios are about 5% and 3%, respectively. The values for positively/negatively charged particles are given in terms of “value1/value2” in the case of the two values being different.
