Fig. 12
Median spectra of population A for the GTC sample (top) and for the spectra for the low-z sample of Bachev et al. (2004; bottom). The continuum has been flattened and the intensity-limit cut set to emphasize faint features that are possibly related to differences in the metal content. The displacement of the two spectra is due to an artificial offset.
