Notes. The full table is only available at the CDS. Column 1 lists the name, Col. 2 the metallicity from the literature source (given in 3); Col. 4 the source of the K-band spectrum; Cols. 5 and 6 give the line indices of Na and CO used for the metallicity determination; Col. 7 gives the derived metallicity determined by us.
