Notes. The data in Cols. 2–6 are the parameters characterizing the atmospheric models selected by the BMF procedure operating solely on photometry and low-resolution spectra (in fact: “degraded” high-resolution spectra, see text), whereas abundances in Cols. 7–9 are derived from the high-resolution HERMES spectra. The last three columns provide the differences between low-resolution and high-resolution abundances.
