Fig. A.1
Wavelength dependence of the ratio R21 of the equivalent widths of narrow DIBs in the lines of sight of HD 204827 and HD 183143 (Hobbs et al. 2008, 2009) confirmed in Fan et al. (2019), derived when a limit of 1.0 Å between narrow and broad DIBs is adopted (Table A.1). These DIBs are shown by red dots, except for the DIBs identified in Table 1 as ζ (Ensor et al. 2017; grey diamonds) or C2 (Thorburn et al. 2003; black triangles).
