All-particle spectrum for the three different EG-CR models: minimal (top), PCS (middle), and UFA (bottom), obtained using WR-CRs (C/He = 0.1) as the additional Galactic component. The proton cut-off energies for the WR-CRs used in the calculation are 2.4 × 10⁸ GeV for the minimal model, 1.5 × 10⁸ GeV for the PCS model, and 1.6 × 10⁸ GeV for the UFA model. The injection energy of the WR-CRs varies within 6% between the three models. SNR-CR spectra are the same as in Fig. 6 (top). Data are the same as in Fig. 2.
