Fig. 6
Spectra of seven red supergiants in Ste 2. Note the prominent DIB at 8620 Å compared to the neighbouring Fe i 8611 Å. The Fe i 8621 Å line can be seen as a bump on the red side of this feature, because it is displaced to λ8624 due to the high vrad of these objects, except in D3, which is too late to show this feature.
