Notes. Columns 2−8: abundances of the observed stars. Column 9: mean abundance for the cluster. Column 10: abundances adopted for the Sun in this paper. Abundances for the Sun are indicated as logϵ(El.). Column 11: number of measured lines for each chemical element. The errors presented for each abundance were calculated by dividing the rms scatter by the square root of the number of the lines used for a given element and a given star. For elements whose abundance was obtained by spectrum-synthesis, the error is the output of the fitting procedure.
