Test of beam purity for iron nuclei (left) and silicon nuclei (right) above the energy Emin using the Auger DNN data (A. Abdul Halim et al. 2025a). The p-values of the χ2 test for a constant elongation rate of a single primary type above Emin (in red) and for Xmax fluctuations consistent with pure nuclei above Emin (in black).
