Figure 12

An example of the systematic uncertainty estimation in 0-5% $\pbpb$ and pp collisions for $3.4 < p \leq 3.6 \gevc$. Upper figure: From left to right: the variation of extracted fractional yields for pions (left panel), kaons (middle panel), and protons (right panel) when the fixed values for the $\mdedx$ and the resolution are randomly varied. Lower figure: the corresponding variation of the particle ratios.
