Caption: Figure 2.

Energy level diagrams for Sc I and Fe I, respectively. The vertical energy scale is the same, and the dashed line shows the ionization energy. The observed lines are marked with red arrows. Note that the near-IR Sc I lines are located at significantly lower excitation energies compared to the near-IR Fe I lines.
