DCO vs. C2 index for stellar and globular cluster spectra. Origin of spectra, symbols and colours as in Fig. 5. Error bars are about the size or smaller than the symbols, thus they are not explicitly shown. Coloured triangles show the measurements for the integrated spectra of LMC globular clusters.
