Figures 1 and 2 show the corrected spectrum ﬁtted with a Levy-Tsallis function. The overall uncertainties (sum in quadrature of statistical and systematical errors) is shown. In order to separate the two contributions to the total uncertainty in the fit parameters, the ﬁt has been performed also with the statistical errors only. Figure 4 shows the mean pt versus particle mass. The < pt > for the Σ∗+ from this analysis has been inserted.
Figure 1: Corrected spectrum for both Σ∗+ and Σ∗− with Levy-Tsallis fit. Statistical and systematical uncertainties are summed in quadrature.
Figure 2: Corrected spectrum for both Anti- Σ∗− and Anti-Σ∗+ with Levy-Tsallis fit. Statistical and systematical uncertainties are summed in quadrature.
