As in Fig. 10, but plotted as a function of Elow. There is a slight upward inflection of values at excitation energies of Elow ≤ 0.25 eV which is possibly a symptom of non-LTE effects in these low-level transitions. Between 3.5 ≤ Elow ≤ 5.0 eV we find an increase in scatter of values, often belonging to higher excitation Fe I transitions. The zoomed subplot shows that a significant number of analysis-independent transitions have multiplets in common, and that the log(g f) values of these multiplets can show significant scatter.
