1D marginalized posterior distributions, showing 1- and 2-sigma credible intervals, for the propagation parameters that were varied in the propagation scan. Light blue: the constraints from p, $\overline{p}$, and He scan, using PAMELA and CREAM data only; Purple: light element scan, fitting Be, B, C, N, and O data. (Given in Table 3.) While most of the propagation parameters overlap between runs, there is a clear (>2σ) separation seen in the Alfvén speed and in the low-energy injection break rigidity ρ_br. Differences in the D₀ − z_h plane can be clearly seen in Figure 3. The injection index for p, $\overline{p}$, and He is also consistently lower below the 220 GV break, suggesting a harder source injection spectrum.
