Correction factors as a function of $\pt$. These are applied to the fractions of pions (left panels), kaons (middle panels), and protons (right panels). Results are presented for peripheral (upper figure) and central (lower figure) $\pbpb$ collisions. The correction to the pion fraction due to the muon contamination is not drawn, but is $\leq 1\%$. Only pions and protons are corrected for feed-down.
