Portion of the spectrum between Hδ and Hγ. Average galaxy spectra of categories SF0 (blue) and SF1 (green) from Dobos et al. (2012) and their division scaled about the average by a factor of five (black) are shown along with normal B8 star HD 152614 (ι Oph; purple) and HgMn star HD 358 (α And; red) from Valdes et al. (2004). Wavelengths of Mn transitions (Kramida & Sansonetti 2013) are marked as orange vertical lines. The feature of keenest interest is that the four strongest Mn features in HD 358 appear as small differential absorptions as one goes from SF1 to SF0 average galaxies.
