Model-to-data ratios of the transverse momentum spectra. The results are shown for two \RT intervals: $0\leq \RT < 0.5$ (top figure) and $2.5\leq \RT < 5$ (bottom figure). The ratios in the toward, away and transverse regions are shown on the left, middle and right column, respectively. The error bars represent the combination of the statistical and systematic uncertainties on the model-to-data ratios.
