Top: same as Fig. 7, but for the two stars HD 169454 and HD 54662 (which were also shown in Fig. 8). Departures are clearly seen around the 9412 Å DIB reported by Galazutdinov et al. (2000); Cordiner et al. (2017). Very weak differences are also seen in the 9428 Å DIB region. Bottom: ratio of the two HD 169454 and HD 54662 spectra. Strong telluric residuals are present, however two additional features are apparent: a P Cygni structure around the 9412 Å DIB, resulting from the DIBs in both spectra, and a depression around 9428 Å. The dashed black vertical line indicates the expected position of the DIB based on laboratory results and corresponds to the center of the depression.
