All-particle energy spectrum for an additional component of EG-CR protons extended down to low energies and modulated by Galactic wind. The numbers within the parentheses denote the injection index for the additional extra-galactic component. For the SNR-CRs, an exponential cut-off energy for protons at 4.1 × 10⁶ GeV is assumed. See text for other details. The EG-Minimal component is the same as in Fig. 9 (top). Data: same as in Fig. 2.
