Notes.
Number of radial velocity measurements added in this program observed with CFHT (C) or SALT (S).
Values corrected for evolutionary status, as reported in Yoon et al. (2016).
1 = single, 2 = binary, from Preston & Sneden (2001), S14 and H16a, 3 = binary from this work.
This star is not in the Yoon et al. (2016) compilation, we report the [C/Fe] from Yong et al. (2013; without evolutionary correction, which is fine since this is not an evolved star), and we computed the A(C) using the Asplund et al. (2009) solar carbon abundance.
Sometimes named 53327–2044–515 (e.g. in Yong et al. 2013), but here we use its official SDSS name.
