Spectra of H2 and H4, constructed by combining signal in areas where Hα emission is at least one half of the peak value in the area observed with GMOS. Wavelengths near Hα and the near-infrared Ca triplet are shown. The spectra have been normalized to the continuum, and corrected for background light by subtracting the mean spectra of adjacent areas. The H4 spectra have been shifted vertically for display purposes. Emission lines are more pronounced in H2 than in H4, suggesting that H2 contains hotter, more massive stars than H4. Wavelengths that sample Ca II lines are contaminated by Paschen series emission, complicating the detection of Ca absorption from luminous red stars.
