Comparison of the intrinsic properties of DBE, computed for different redshifts, with the Amati relation (a) and the Yonetoku relation (b). The green line in each panel shows the corresponding relation, with the green-shaded area indicating its 3σ scatter. The colored lines display E_p, z as a function of E_iso (left) and L_iso (right), computed for spectra D, B, and E (distinguished by line style) as a function of z, encoded by the color map. Circles on top of each curve denote reference redshift values, z = 0.1, 1, 2. The blue-shaded bands indicate the 1σ confidence intervals (for spectrum B in the left panel; for spectra D, B, and E in the right panel), while the blue dots denote regions corresponding to lower limits on the fitted E_p (for D, E, and D+B+E in the left panel).
