Proton flux obtained for the min diffusion model (see below) and a source frequency μ = 3century-1. The band displays the standard deviation σφ obtained analytically, with a lower cut-off on the ages of the sources tmin = 100years. The blue symbols indicate the flux measured by CREAM (Yoon et al. 2011) and PAMELA (Adriani et al. 2011).
