Simplified Gaussian profiles of the bump for different UV bump parameters. The positions and widths of the red (resp. black) profiles correspond to the extrema of the fit linear relationships in Fig. 1, marked by letters A (resp. B) in the two top graphs, corresponding to the 5780 Å DIB. The bump height and the continuum were derived from fit bump height and bump-over-continuum relationships for the same DIB (see text). The position and width of the violet profile are those of the JADES-GS-z6-0 galaxy. The bump height and the continuum were derived by extrapolation of the fit linear relationships to the value EW(5780)/EBV = 2500 (point J in top graph of Fig 1).
