AMS-02 mock data for the elemental fluxes φ_B and φ_Ca) and their ratio b), using the input model CC # 2 of Table 2 and assuming a detector exposure factor F = 150 m² sr day. The error bars are only statistics. The constraints to the transport parameters provided by the AMS-02 mock data are reported by the 3-σ contour levels for exposure factors of F = 12, 36, and 150 m² sr day in c) and d). The data are fitted within the reference model (star in panel c) and dotted line in panel b)) and within the model CC # 2 (cross in panel d) and solid line in panel b)). The AMS-02 discrimination probability between the two models as a function of the systematic error in the measurement is shown in d) for F = 12, 36, and 150 m² sr day. The systematic errors are assumed to be energy-independent.
