Final Bethe-Bloch (upper figure) and resolution (lower figure) curves obtained as described in the text. Results are shown for pp (left panels) and 0-5% $\pbpb$ (right panels) collisions. The Bethe-Bloch curve is shown in the region relevant for pions, kaons, and protons in this analysis. The external PID data samples of pions, protons and electrons are used to obtain the parameterizations, these data are plotted as markers. The shaded areas represent the systematic uncertainty of the parameterizations.
