Figure 5.

Secondary-to-primary ratio 68% and 95% posterior bands from our light element (Be–Si) scan, shown in magenta in Figure 1. The $\overline{p}∕p$ ratio is shown to indicate that using the same propagation parameters for hydrogen yields a very bad fit to the data. Data shown are HEAO (blue), CREAM (green), ACE (light blue), ISOMAX (black), and PAMELA (red). The best fit is shown as a black line, and the dashed lines correspond to the LIS (unmodulated) ratios. In the left-hand panel, we use the HEAO modulation posterior, and the solid line uses the HEAO best-fit modulation potential. The dash-dotted line is the modulated spectrum using the best fit to the ACE-CRIS modulation potential; for clarity we do not show the posterior intervals for this case. Correspondingly, the central plot uses the ACE modulation (BF in black), and we show the best fit using the ISOMAX best-fit modulation potential with a dash–dotted line.
