Fig. 10


Mean spectra of the classes in the wavelength range from 16 178 to 16 222 Å, where the differences among classes are particularly enhanced. Top to bottom: mean spectra for classes belonging to groups from 0 to 7. Each mean spectrum is drawn with the same colours used in Fig. 7. In all panels we plot the spectral windows used in ASPCAP to determine the chemical abundances of stars. Each set of element windows is colour-coded as indicated in the legend of the first panel.
