Notes. For convenience, the last rows of the table refer to our results on NGC 2808 from Paper I. The right-most two columns list the metallicities derived from RGB stars by Carretta et al. (2009) for NGC 104, NGC 6121, and NGC 6809, with the associated errors being the total star-to-star errors in their Table A.3, while the data for NGC 2808 are from Carretta et al. (2006).
