Notes. We show here a part of Table 3 to display the structure and content. The whole table can be found in electronic form at the CDS. It contains the main atmospheric parameters and determined abundances for up to 28 chemical elements in 45 starts of NGC 1851. “Star” – the GES target identifier, “T_eff” – effective temperatures, “e_T_eff” – uncertainty of the effective temperature, “log g” – surface gravity, “e_log g” – uncertainty of surface gravity, “[Fe/H]” – metallicity, “e_[Fe/H]” – uncertainty of metallicity, “v_t” – microturbulent velocity, “e_v_t” – uncertainty of microturbulent velocity, “[El/H]” – element abundance in relation to hydrogen, “σ” – abundance scatter between multiple lines for the same star, “nl” – number of lines used for the abundance determination.
