Strong absorption lines of key H- and He-like ions were visually identified initially, and we modeled them using a series of Gaussian absorption functions (gabs ) with physical properties listed in Table 3. For thoroughness, we also identified additional potential spectral features using a blind line search described in the Appendix. For these key lines, we obtained the ionic column densities () from the following relationship between and for the unsaturated absorption lines (Spitzer, 1978, Ch. 3):
Table 3 lists the measured outflow velocity ( ). and the line equivalent width ( ) in mÅ from the absorption lines. The turbulent velocity width is estimated from the FWHM ( , where is the velocity dispersion) of the line profile using . The ionic column density is derived using equation (3).
