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

Table 3

Parameter values corresponding to the dashed curves in Figure 1. The relative errors for the effective temperatures, chemical potentials, and ratios are about 5%, 10%, 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.
