CR spectra of the two models. The spectrum of run-away CRs integrated until the present time (37 kyr) and the total leaked CRs from W28-North at 25 kyr are marked as solid and dashed lines, respectively. The leaked CRs consist of two parts, the PL (Γ_CR = −2.0) up to E_max, and the high-energy tail. The normalization for the dashed lines has been multiplied 10 times for graphical purposes.
