Carbon abundances in all the CEMP stars in the present paper and in the literature with [Fe/H] > −3.5 (Sivarani et al. 2006; Thompson et al. 2008; Aoki et al. 2008; Behara et al. 2010; Placco et al. 2011; Carollo et al. 2012; Masseron et al. 2010, 2012; Yong et al. 2013; Cohen et al. 2013; Spite et al. 2013; Caffau et al. 2013a). The bimodal distribution is clear in this plot. We refer to the peak at lower carbon abundance as the low-carbon band and to the peak at higher carbon abundance as the high-carbon band.
