Isotopic ratios of Li, Be, and B (from top to bottom panel) calculated from the best-fit models to AMS-02 LiBeB/C (at fixed L = 5 kpc). The production cross-section sets considered are the original Galp-opt12 (dotted lines) and the updated sets OPT12 (dashed lines), OPT12up22 (solid lines), and OPT22 (dash-dotted lines); the suffix ‘-U’ in the labels recalls that we use here unbiased cross-section sets, see Eq. (11). The data are from IMP (Garcia-Munoz et al. 1977a,b, 1981), Balloon ’73/08 (Hagen et al. 1977), Balloon ’77/05 (Buffington et al. 1978), Balloon ’77/09 (Webber & Kish 1979), Balloon ’70/06 (Bjarle et al. 1979), ISEE3 (Wiedenbeck & Greiner 1980; Mewaldt et al. 1981; Krombel & Wiedenbeck 1988), HEIST (Gibner et al. 1992), Ulysses (Connell 1998), Voyager1&2 (Lukasiak 1999), SMILI-II (Ahlen et al. 2000), ISOMAX (Hams et al. 2004), ACE (Yanasak et al. 2001; de Nolfo et al. 2006), AMS-01 (Aguilar et al. 2011), PAMELA (Menn et al. 2018; Nozzoli & Cernetti 2021).
