Spectrum in the G-band region for the C-rich star BS16 (Teff = 5961 K), compared with the spectra for a C-normal star B10 (Teff = 5940 K) and C-poor star B16 (Teff = 5985 K). Spectra have been offset vertically for a clearer display. The spectral ranges used for the derivation of our CH index are shown as shaded areas, for easier comparison. The horizontal dashed line is at the average value within the “continuum” reference band (4315.9−4317.9 Å).
