"Figure 3.1" of "Direct observation of dijets in central Au + Au collisions at s(NN)**(1/2) = 200-GeV."

Centrality dependence (number of participants Npart) of away-side ($|\Delta\phi-\pi|$<0.63) yields in d+Au and Au+Au collisions at 200 GeV, for $8 < p_T^{trig} < 15$ GeV/c and various $p_T^{assoc}$ ranges. Data for $3 < p_T^{assoc} < 4$ GeV/c are scaled by 1.5 for clarity. The point with the smallest Npart is the yield in d+Au collisions and the others are those in Au+Au collisions.
