Figure 17

 Transverse momentum $\pt$ distribution of total protons based on tracks reconstructed using only TPC information (full circles) compared to primary protons (open circles) and corresponding total spectra measured by the STAR collaboration in Au-Au collisions at $\snn=200$ GeV (full stars). 0-5% most central events. Box: systematic uncertainty; Statistical uncertainties smaller than the symbols; curve: individual blast wave fit.
