Notes. Column 1 lists the RGB star ID. Columns 2 and 4 list the [Fe/H] and [Ca/H], respectively, with total errors in the abundances as indicated. N indicates the number of lines measured for the determination of [Fe/H] and [Ca/H], as indicated. χ2 indicates that the corresponding abundance was determined through a χ2-test using a grid of synthetic spectra (see Sects. 4.2.3 and 4.3.3). Column 6 lists [Ca/Fe].
