Average expansion velocity (\avBt) and kinetic freeze-out temperature (\Tkin) progression from the simultaneous Boltzmann-Gibbs blast-wave fit to \ppipm, \pkapm and p(\pprm) spectra measured in \pbpb collisions at \snnF and 2.76 TeV The correlated uncertainties from the global fit are shown as ellipses The elliptic contours correspond to 1$\sigma$ uncertainties, with statistical and systematic uncertainties being added in quadrature
