Best-fit models from the combined analysis of AMS-02 Li/C, Be/B, and B/C data with USINE (see Table 1). The four line styles correspond to the four production cross-section sets discussed in Sect. 3.1 (Galp-opt12, OPT12, OPT12up22, and OPT22). We also show 1σ CLs, but for the OPT12up22 set only (solid black lines), the other sets giving similar contours. Top panel: Be/B as a function of rigidity, along with the AMS-02 data (Aguilar et al. 2018) used for the fit. Bottom panel: ¹⁰Be/⁹Be as a function of kinetic energy per nucleon for the same transport parameters and L as above (i.e., from best-fit to Li/C, Be/B, and B/C data only, no fit to ¹⁰Be/⁹Be). A compilation of data (green symbols) is shown for illustrative purpose.
