Constraints on the halo size L from the analysis of 10Be/9Be data with the analytical formula.

Notes. The first three columns report the production cross-section sets and their associated diffusion time tdiff, and the asymptotic high-energy value ℱHe calculated from Maurin et al. (2022). The next columns report the best-fit L (and uncertainties) for the analysis based on the approximation ℱ = ℱHE or from the use of the full energy dependence in ℱ(Ek/n). We also show, for the two cases, the associated reduced χ2 (14 data points, 13 degrees of freedom).
