Normalized globular cluster spectra that have been offset by one unit
Normalized globular cluster spectra that have been offset by one unit. These spectra have not been de-redshifted. These sample spectra show the wavelength range that the majority of our spectra cover and display the range of S/N and metallicity present. The spectrum of g1426 shows emission features around 5000 Å and 5890 Å of unknown origin. The planetary nebulae hosting globular cluster, g1420, is also plotted and the emission due to 4959 and 5007 Å [OIII] lines can be seen redshifted to 4971 and 5019 Å.
