Appendix A: Ratios of various elements to calcium

For the reader’s convenience we present in the following table the data that were used to plot Fig. 7. All the published ratios have been scaled to bring them to our adopted solar abundance scale. As solar reference for carbon, nitrogen, oxygen, and iron we took Caffau et al. (2011), and for the other elements Lodders et al. (2009).

Table A.1

[X/Ca] ratios for the four low-carbon band stars studied in the present paper and for the carbon-normal most metal-poor star SDSS J1029+1729.

Table A.2

[X/Ca] ratios for all the known CEMP stars with [Fe/H] less than about −4.0.

Table A.3

Abundances of Fe, Ca, and C for the sample of nine comparison stars.
