Top panels: values obtained for the /d.o.f. and the fit parameters (and uncertainties) as a function of for propagation models A (left) and B (right) and for the full acceptance error (blue) and the split acceptance error (orange). In the case of split acceptance error, corresponds to the correlation length of the Acc. res. contribution only. Bottom panels: comparison of best-fit B/C (lines) and AMS-02 data (symbols) for the above models and configurations, i.e. full (blue lines, top) vs. split (orange lines, bottom) acceptance errors. Only a sample of correlation lengths are shown (0.015, 0.1, and 1 decade).
