Comparison of original (Galp-opt22, thin black lines labelled ‘OLD XS’) and updated (OPT22, thick coloured lines labelled ‘NEW XS’) production cross sections, for ⁵⁶Fe (left) and ¹⁶O (right) fragmenting into Be isotopes. The two branches seen in some of the updated cross sections above 1.5 GeV/n illustrate two different procedures to update them (fit of a constant or spline passing through the data, see Sect. 3.2.1). The ratio of the values in these two branches at high energy corresponds to the values shown in Table 2.
