Caption: Figure 3.

Spectra of the five template clusters used to suppress the stellar continuum and enhance the visibility of emission lines. The strongest absorption in this part of the spectrum comes from Hβ; most of the others lines are due to iron. The differences between spectra represent variations in cluster's age and metallicity.
