Fig. 2
The average line-to-continuum-ratios of the ZrO and TiO absorption bands within the spectral range of WHT and SAAO low-resolution spectra (i.e. ZrO and TiO indices) for all stars in the sample. The size of the symbols increases with [s/Fe] and the color varies with C/O. Crosses indicate stars for which Teff, C/O and [s/Fe] are unknown.
