Fig. 6
Region of the molecular CH band. The gray plusses are the observed spectra for the Sculptor target stars, the colored lines are synthetic spectra for [C/Fe] = −2.0 (black), [C/Fe] = −1.0 (green), [C/Fe] = + 0.0 (blue), [C/Fe] = + 1.0 (magenta). For Scl051_05 and Scl024_01, the best fitting synthetic spectra are overplotted in red and have [C/Fe] = −0.4 and [C/Fe] = −0.5 respectively.
