Caption: Figure 4.

The strong intermediate-mass element lines (top row) and iron group element lines (bottom row). The blue lines are the data and the red dashed lines are a Gaussian fit to the feature. The argon lines are broader and somewhat more asymmetric in velocity space with red or blueshifts. The [Ca II] doublet is resolved, as is the Ca IR triplet. [Ca II] shows a very symmetric line shape, while the [Fe III] has a small redshift and the [Co II] line has a more marked redshift. The Gaussian fit results are shown in Table 4.
