$\begin{figure} \par\includegraphics[width=7cm,clip]{9073fig1.eps}\end{figure}$ Figure 1: Ratio of effective collision strengths between the present 36- and 40-configuration calculations at T=9.8 $\times$ 10⁷ K. Only transitions from the ground level are shown. Circled points correspond to transitions where the final level is poorly matched (overlap less than 0.9) between the two calculations.

$\begin{figure} \par\includegraphics[width=6.9cm,clip]{9073fig9.eps}\end{figure}$ Figure 9: Comparison of results from Zeng et al. (2005) to the present 40-configuration results at T=5.80 $\times$ 10⁶ K. Points represent transitions from the ground configuration to levels in the 3d³ (circles), 4p (triangles), and 4f (squares) configurations. On the x-axis is shown the ratio of the A-coefficients from the Zeng et al. calculation to the present calculation; on the y-axis is the analagous ratio of the effective collision strengths. The dotted and dashed boxes correspond to agreement within 20% and 50%. The solid line marks where the ratios agree.
