Notes. The ‘Nr’ denotes the number of lines used to calculate abundance (including blends), log ϵ denotes the average abundances (on the scale in which log ϵ(H) = 12), σ denotes the standard deviation in cases where the fit was based on more than three lines, log ϵ (Sun) denotes the solar abundance (Asplund et al. 2009).
