Notes. The values for the parameters of this table are medians. Numbers in parentheses show the standard deviation for the value, not the standard deviation of the mean. The number of stars with the best quality flag (flag_X_fe=0) is shown under the parameter. If for a certain element only a single star with good quality abundance was left, no standard deviation is shown. Abundances of Li and C, affected by stellar evolution in giants, were excluded.
