Figure 14

Measurement of $v_2\{\rm SP\}$ as a function of $\pt$, for the unbiased sample and for the large-$q_2$ sample (top panel) and ratio between the large-$q_2$ result over the unbiased result (bottom panel). Data points (full markers) are compared with AMPT Monte Carlo model (bands). Only statistical uncertainties are plotted (systematic uncertainties are smaller than the markers).
